Custom Sportswear Manufacturing Guide for Brands & Startups

Custom sportswear manufacturing is one of the most important operational decisions a sportswear brand makes.

A strong design can attract attention.

A strong logo can build recognition.

Good marketing can generate the first sale.

But if the product behind the brand is inconsistent, uncomfortable, badly fitted or difficult to reproduce, growth becomes much harder.

Sportswear manufacturing has to translate a design into a physical product that can perform repeatedly across:

• Different sizes
• Different production batches
• Different colours
• Different customers
• Different seasons
• Future reorders

That requires more than cutting and sewing.

A complete sportswear manufacturing system connects:

Product planning → Fabric and trim sourcing → Sampling → Fit approval → Size grading → Branding → Bulk production → Quality control → Packaging → Fulfillment → Repeat manufacturing

For startups, this structure reduces costly development mistakes.

For established brands, wholesalers and distributors, it creates consistency at scale.

GHC Sportswear® supports sportswear brands, private label businesses, retailers, gyms, clubs, wholesalers and distributors with custom product development, sampling, OEM/ODM manufacturing, branding, packaging and bulk production.

What Is Custom Sportswear Manufacturing?

Custom sportswear manufacturing is the process of developing and producing performance or sports-inspired apparel according to a buyer’s own specifications.

Those specifications may control:

• Product design
• Fabric
• GSM
• Stretch
• Fit
• Size range
• Colours
• Panels
• Pockets
• Zippers
• Logos
• Printing
• Embroidery
• Labels
• Packaging

This is different from simply buying an existing garment and adding a logo.

A genuinely custom manufacturing project may change the entire product.

For example, a brand developing performance leggings might specify:

• 78% nylon / 22% elastane
• High-rise waistband
• Four-way stretch
• Matte finish
• Full-length inseam
• Hidden waistband pocket
• Flatlock seams
• Silicone logo
• Custom woven labels
• Branded packaging

The manufacturer then has to convert those requirements into a repeatable production specification.

That is the real purpose of custom sportswear manufacturing.

Why Sportswear Manufacturing Requires More Control Than Basic Apparel

Sportswear is exposed to greater physical demands than many ordinary garments.

Depending on the activity, products may experience:

• Stretching
• Sweating
• Repeated washing
• Abrasion
• Running
• Jumping
• Squatting
• Lifting
• Contact
• Outdoor use

A casual T-shirt may perform adequately if it is comfortable and visually acceptable.

A compression top or riding legging has additional requirements.

It may need:

• Controlled stretch
• Strong recovery
• Stable seams
• Correct fit under movement
• Moisture management
• Opacity
• Shape retention

This means sportswear should be developed from the intended activity backwards.

The question is not simply:

“What fabric looks good?”

The stronger question is:

“What does this garment need to do during actual use?”

The Custom Sportswear Manufacturing Process

A well-managed project moves through defined stages.

Stage	Main Purpose	Key Output
Product planning	Define what will be manufactured	Product specification
Fabric and trim sourcing	Match materials to performance and design	Approved materials
Sampling	Convert specifications into a physical garment	Approved sample
Fit and sizing	Establish measurements and grading	Size system
Branding development	Approve logos, labels and decoration	Branding standards
Pre-production approval	Lock bulk-production details	Production reference
Bulk manufacturing	Reproduce the approved product	Finished garments
Quality control	Verify conformity	Approved bulk goods
Packaging	Prepare garments for sale or distribution	Packed products
Fulfillment	Prepare and dispatch the order	Shipment
Reorder control	Preserve specifications	Repeatable production

Each stage depends on the quality of the stage before it.

Starting bulk production before product development is properly controlled simply pushes unresolved problems further into the manufacturing process.

Product Planning Comes Before Sampling

Many manufacturing problems begin before fabric is cut.

A buyer sends:

“I need premium gym wear.”

That is not yet a production specification.

The manufacturer still needs to understand:

• What product?
• For men or women?
• Fitted or relaxed?
• What fabric?
• What weight?
• What stretch?
• What climate?
• What performance level?
• Which colours?
• Which sizes?
• Which logo method?
• Which packaging?

The more uncertainty that remains at the start, the more revisions are likely later.

A structured product-planning process should define the product before manufacturing investment increases.

For deeper planning guidance, see Apparel Manufacturing Product Planning.

What Should a Sportswear Tech Pack Include?

A tech pack acts as the technical communication document between buyer and manufacturer.

Depending on the product, it can contain:

• Front and back sketches
• Product description
• Measurement chart
• Construction notes
• Fabric specification
• GSM
• Colour references
• Trim details
• Stitching
• Logo dimensions
• Logo positions
• Labels
• Packaging
• Care instructions

A tech pack should answer as many manufacturing questions as possible before sampling begins.

However, startups without a complete technical pack can still begin development using:

• Reference garments
• Detailed images
• Measurements
• Written specifications
• Design files

The important requirement is that uncertainty is progressively converted into documented decisions.

Two Common Product Development Routes

Brands often begin through one of two methods.

Physical Reference Sample

The buyer sends an existing garment that represents the desired:

• Fit
• Construction
• Fabric direction
• Measurements
• Finishing

The reference can then be reviewed and adapted.

This method can reduce interpretation errors because the manufacturer can physically inspect the product.

Tech Pack, Images and Specifications

The buyer provides:

• Drawings
• Images
• Measurements
• Fabric requirements
• Branding
• Construction details

The manufacturer develops the product through sampling.

Both routes can work.

The better route depends on how much product information the buyer already has.

Fabric Selection Is a Performance Decision

Fabric is one of the most important variables in custom sportswear manufacturing.

It affects:

• Comfort
• Stretch
• Recovery
• Breathability
• Moisture behaviour
• Weight
• Durability
• Printing
• Shape retention
• Cost

Sportswear fabrics frequently include:

• Polyester
• Polyester-spandex
• Nylon-spandex
• Interlock knits
• Jersey knits
• Mesh
• Scuba-style knits
• Fleece
• Technical stretch fabrics

Textile Exchange describes polyester as widely used across apparel because of characteristics including strength, durability and relatively fast drying.

But fibre content alone does not tell the whole story.

Two fabrics can both contain 90% polyester and 10% elastane while performing differently because of:

• Yarn
• Knit construction
• GSM
• Finishing
• Stretch direction
• Recovery
• Surface treatment

Buyers should therefore evaluate the actual fabric rather than relying only on fibre percentages.

Understanding GSM

GSM means grams per square metre.

It is a common way to describe fabric weight.

Higher GSM generally means more material per square metre, but it does not automatically mean higher quality.

For example:

• A lightweight running shirt may intentionally use a low GSM.
• A compression legging may require denser fabric.
• A winter tracksuit may require greater weight.
• A training jersey may prioritise airflow over thickness.

The correct GSM depends on the product.

Sportswear development should therefore avoid the simplistic rule:

Heavier = better.

The better rule is:

Suitable weight = better.

Fabric Direction by Sportswear Product

Product	Typical Fabric Direction	Main Requirement
Gym T-shirt	Lightweight polyester performance knit	Breathability and moisture management
Compression top	Polyester-spandex or nylon-spandex	Stretch and recovery
Leggings	Dense high-stretch knit	Fit, recovery and opacity
Sports bra	Supportive stretch construction	Recovery and support
Tracksuit	Interlock, scuba or technical knit	Structure and comfort
Training shorts	Lightweight stretch or woven fabric	Movement
Hoodie	Cotton-poly fleece or performance fleece	Comfort and warmth
Running jacket	Lightweight technical woven	Low weight and weather management
Base layer	Stretch technical knit	Close fit and moisture control

These are manufacturing directions, not universal specifications.

The final material should match the target product.

Fabric Testing Before Bulk Production

A serious sportswear project may require evaluation of fabric performance before bulk approval.

Depending on the product, buyers may consider:

• Stretch
• Recovery
• Pilling
• Colourfastness
• Shrinkage
• Abrasion
• Moisture management
• Opacity

Not every product requires laboratory testing.

But buyers should identify critical performance requirements before production begins.

For example, a gym legging brand may care heavily about:

• Stretch recovery
• Pilling
• Squat opacity
• Colourfastness

A hoodie brand may prioritize:

• Shrinkage
• Pilling
• Colour consistency
• Fabric weight

Testing requirements should reflect real product risk.

Fabric and Trim Sourcing Must Be Controlled Together

Sportswear is not made from fabric alone.

Trims may include:

• Zippers
• Elastic
• Drawcord
• Cord ends
• Snaps
• Thread
• Labels
• Patches
• Reflective tape
• Silicone badges
• Packaging

A high-quality fabric combined with a weak zipper still creates a weak product.

This is why material sourcing should evaluate the entire garment system.

The broader sourcing process is covered in Fabric and Trim Sourcing.

Sampling Turns the Idea Into a Product

Sampling is one of the most important stages of sportswear manufacturing.

The sample allows the buyer to evaluate whether the design works physically.

A sportswear sample can reveal:

• Incorrect fit
• Wrong garment length
• Unsuitable fabric
• Weak stretch
• Poor pocket placement
• Incorrect logo size
• Colour problems
• Construction issues

Digital artwork cannot reveal all of these.

A garment needs to be made, worn and reviewed.

Read the complete Apparel Sampling Process for the wider sampling framework.

Common Sportswear Sample Types

Depending on the project, development may include:

Prototype Sample

Used to translate the first design into a physical product.

Fit Sample

Used primarily to review:

• Measurements
• Shape
• Movement
• Comfort

Revised Sample

Produced after corrections.

Size Set

Used to review grading across several sizes.

Pre-Production Sample

Represents the approved specification before bulk manufacturing begins.

Not every order requires every sample type.

But the sample stage should provide enough confidence to release bulk production responsibly.

Fit Is Part of Product Performance

Sportswear fit affects more than appearance.

A garment that is too tight may:

• Restrict movement
• Create discomfort
• Distort seams

A garment that is too loose may:

• Move excessively
• Reduce intended support
• Change visual positioning

Different sportswear categories require different fits.

A compression legging and oversized training shirt should not be developed from the same fit logic.

Fit may be:

• Compression
• Fitted
• Athletic
• Regular
• Relaxed
• Oversized

The intended fit should be written into the product specification rather than left to interpretation.

Sportswear Sizing Needs Consistency

Sizing can become a major commercial problem when batches change.

Imagine:

First production: Medium fits customer correctly.

Second production: Medium fits like Small.

Even if both garments are individually well made, the brand now has a consistency problem.

That affects:

• Customer confidence
• Retailer trust
• Returns
• Reviews
• Reorders

The manufacturer should therefore retain:

• Measurement charts
• Patterns
• Grading
• Approved samples
• Production references

Consistency between batches is as important as consistency inside one order.

Men’s, Women’s and Unisex Fits

A sportswear collection may use:

• Men’s patterns
• Women’s patterns
• Unisex patterns

These should not be treated as interchangeable by simply changing size labels.

Depending on product positioning, women’s products may require different:

• Chest proportions
• Waist shaping
• Hip shaping
• Rise
• Inseam
• Garment length

Men’s and unisex patterns may also require different body proportions.

The brand should define its intended customer before sizing is developed.

Stretch and Recovery

Stretch fabric must return toward its original shape after movement.

If recovery is weak, products may:

• Bag at the knees
• Sag at the waistband
• Stretch around elbows
• Lose compression
• Change appearance after wear

This is particularly important in:

• Leggings
• Sports bras
• Compression garments
• Base layers
• Cycling apparel

Fabric stretch should therefore be considered together with recovery.

Maximum stretch alone is not enough.

Opacity in Leggings and Compression Bottoms

Opacity becomes important for fitted lower-body products.

A fabric may appear opaque while lying flat but become more transparent when stretched.

For products such as:

• Gym leggings
• Yoga leggings
• Compression tights
• Riding leggings

the material should be evaluated under realistic extension.

This is commonly referred to by consumers as squat-proof performance.

The requirement should be checked during sampling rather than discovered through customer reviews.

Seam Construction Matters

Sportswear seams are exposed to repeated movement.

Construction may use:

• Overlock
• Coverstitch
• Flatlock
• Reinforced seams
• Conventional lockstitch in selected areas

The correct method depends on:

• Fabric
• Stretch
• Garment type
• Seam position

A highly stretchable fabric joined with an unsuitable rigid construction may fail even when the material itself is excellent.

Product performance depends on how all components work together.

Sportswear Branding and Surface Design

Branding turns a technically sound garment into a recognizable branded product.

Sportswear decoration methods may include:

• Sublimation
• Screen printing
• Heat transfer
• DTF
• Embroidery
• Silicone logos
• Rubber patches
• Woven labels

Each method affects the product differently.

A large embroidery may work well on a hoodie but be unsuitable for a lightweight fitted running shirt.

A heavy transfer may change the hand feel of a breathable technical panel.

The decoration method should therefore be selected with the garment, not after it.

For the complete decoration framework, read Surface Design Apparel.

Sublimation

Sublimation is particularly relevant for polyester sportswear.

It can support:

• Full-colour designs
• Gradients
• Patterns
• Numbers
• Names
• Sponsor graphics
• All-over artwork

Because the design is integrated into suitable polyester material, sublimation can maintain a lightweight surface.

It is widely used for:

• Football uniforms
• Basketball kits
• Cycling apparel
• Running shirts
• Training garments

Heat Transfer

Heat transfer is frequently used for:

• Small logos
• Player names
• Numbers
• Sponsor marks
• Reflective details

Its performance depends on:

• Film
• Adhesive
• Heat
• Pressure
• Time
• Fabric compatibility

The logo should be tested on the actual production fabric.

Embroidery

Embroidery offers a textured premium appearance.

It works particularly well on:

• Hoodies
• Tracksuits
• Jackets
• Polo shirts
• Caps
• Bags

However, embroidery adds stitch density and local stiffness.

That makes it less appropriate for some lightweight, highly stretchable garments.

Method selection should follow product function.

Private Label Sportswear Manufacturing

Private label manufacturing allows a brand to sell products under its own identity without owning the manufacturing facility.

Private label customization can include:

• Custom design
• Fabric
• Colours
• Logo
• Woven labels
• Size labels
• Care labels
• Hang tags
• Packaging

The brand remains visible to the customer.

The manufacturer supports the product-development and production process.

For a full explanation, see the Private Label Apparel Manufacturing Guide.

OEM Sportswear Manufacturing

OEM commonly refers to manufacturing products according to the buyer’s own specifications.

For example, the buyer may provide:

• Tech pack
• Fabric
• Measurements
• Artwork
• Packaging

The manufacturer produces according to those requirements.

This model suits brands that already have a developed product concept.

ODM Sportswear Manufacturing

ODM generally involves more manufacturer participation in the development process.

A buyer may provide:

• Product idea
• Target market
• Reference images
• Performance requirements

The manufacturer then helps convert those requirements into a manufacturable product.

The exact division between OEM and ODM varies between companies.

The most important point is to define who is responsible for each product-development decision.

Bulk Production Begins After Approval

Bulk production should begin only when the buyer and manufacturer have clearly agreed on the product.

That normally means approving:

• Fabric
• Colour
• Measurements
• Fit
• Construction
• Branding
• Labels
• Packaging

The production team should work from controlled specifications.

Not scattered messages.

Not old files.

Not assumptions.

This connects sportswear manufacturing directly with Controlled Manufacturing.

Production Planning

Before cutting bulk fabric, manufacturing should consider:

• Order quantity
• Material availability
• Colour quantities
• Size breakdown
• Printing requirements
• Embroidery requirements
• Sewing capacity
• Packaging
• Delivery timing

A manufacturing schedule should coordinate these stages.

For example:

Fabric available + branding not ready = delay

Printing complete + trims missing = delay

Garments finished + packaging missing = delay

A strong production plan considers the full order rather than one department at a time.

Cutting

Cutting converts fabric into garment components.

Accuracy matters because cutting influences:

• Measurements
• Symmetry
• Panel alignment
• Fabric consumption

Stretch materials also require appropriate handling.

Errors made during cutting affect every subsequent production stage.

Printing and Embroidery Before Assembly

Some branding applications must be completed before the garment is fully sewn.

For example:

• Sublimated panels
• Screen-printed panels
• Embroidered chest pieces

Applying decoration at the correct production stage reduces handling problems.

This should be planned during sampling.

Sewing and Assembly

During sewing, production should control:

• Seam type
• Stitch density
• Thread
• Measurements
• Panel matching
• Reinforcement
• Trim installation

Sportswear requires particular attention at high-stress areas.

These may include:

• Crotch seams
• Armholes
• Waistbands
• Pocket openings
• Zipper ends
• Shoulder seams

Construction should match the intended movement.

Quality Control Should Happen During Production

Waiting until all garments are finished is risky.

A better quality-control structure may include:

Incoming Material Check

Confirm fabric and trims.

First-Piece Check

Confirm the first pieces coming from production.

In-Line Inspection

Identify recurring defects while production continues.

End-Line Inspection

Review completed garments.

Final Inspection

Check finished order before packing or release.

Quality is easier to protect when errors are stopped early.

What Sportswear Quality Control Should Check

Depending on the product, inspection may cover:

• Fabric
• Colour
• Measurements
• Stitching
• Seams
• Zippers
• Pockets
• Logos
• Print placement
• Labels
• Finishing
• Packaging

Typical defects may include:

• Skipped stitches
• Open seams
• Uneven measurements
• Incorrect logo position
• Wrong colour
• Damaged fabric
• Stains
• Missing labels

The accepted tolerance and inspection requirement should reflect the buyer’s project.

Packaging Is Part of the Product

Packaging protects the garment and communicates the brand.

Private label sportswear packaging can include:

• Individual polybags
• Recyclable or paper-based alternatives
• Size stickers
• Barcode labels
• Branded bags
• Tissue
• Hang tags
• Cartons

The packaging specification should be decided before the end of production.

For the complete framework, read Apparel Packaging.

Order Fulfillment

Manufacturing is not complete simply because garments have passed sewing.

Orders still need to be:

• Counted
• Sorted
• Packed
• Verified
• Documented
• Prepared for dispatch

For B2B orders containing multiple:

• Styles
• Sizes
• Colours
• SKUs

fulfillment accuracy becomes increasingly important.

See the Order Fulfillment Process for the full manufacturing-side fulfillment framework.

Repeat Production Is Where Manufacturing Systems Are Tested

A startup may initially focus on getting the first order right.

A mature brand also asks:

Can the supplier reproduce this product six months later?

Repeat production depends on retained references such as:

• Pattern
• Size chart
• Fabric
• Colour
• Artwork
• Logo dimensions
• Labels
• Packaging
• Approved sample

If these records disappear, every reorder becomes another development project.

Repeatability is therefore a major part of supplier value.

Sportswear Product Categories

A sportswear manufacturer may support many different products.

Examples include:

• Gym T-shirts
• Training tops
• Compression wear
• Tracksuits
• Hoodies
• Jackets
• Shorts
• Leggings
• Sports bras
• Yoga wear
• Running apparel
• Cycling apparel
• Team training wear
• Sports uniforms
• Lifestyle sportswear

These categories do not all require the same:

• Fabric
• Pattern
• Machine setup
• Decoration
• Quality checks

Manufacturing capability should be assessed by product rather than by generic claims.

Explore the wider GHC Sportswear® product range.

Custom Sports Uniforms vs General Sportswear

Sports uniforms are a specialized part of the broader sportswear category.

They often require:

• Team colours
• Player numbers
• Player names
• Sponsor logos
• Club identity
• Competition requirements
• Repeat replacement pieces

General sportswear may focus more heavily on:

• Retail collections
• Gym use
• Running
• Lifestyle apparel
• Individual consumer sizing

For detailed teamwear development, use the dedicated Custom Sports Uniforms Guide.

This keeps the two pillar topics clearly separated:

Custom Sportswear Manufacturing Guide = manufacturing system

Custom Sports Uniforms Guide = teamwear and uniform system

Sportswear Manufacturing for Startups

Startups face a unique challenge.

They need enough customization to create a real brand without creating unnecessary complexity before demand is proven.

A practical first collection might use:

• Fewer styles
• Controlled colourways
• Shared fabrics
• Limited trim options
• Consistent branding

This makes:

• Sampling easier
• Production easier
• Inventory easier
• Reorders easier

A startup does not need twenty products to appear serious.

It needs a small number of products that are developed properly.

Minimum Order Quantity

MOQ depends on factors such as:

• Product
• Fabric
• Colour
• Decoration
• Custom trims
• Supplier minimums

GHC Sportswear® can support low-quantity development, including MOQ options as low as 1 depending on the specific product and project.

However, very small quantities and bulk production do not have identical economics.

Larger orders can distribute costs associated with:

• Patterns
• Artwork
• Printing setup
• Custom labels
• Moulds
• Material purchasing

Buyers should evaluate quantity together with long-term order planning.

Common Sportswear Manufacturing Mistakes

Brands can reduce unnecessary delays and costs by avoiding recurring mistakes.

No Clear Specification

If nobody knows exactly what is being made, sampling becomes guesswork.

Choosing Fabric by Appearance Only

Sportswear material must perform.

Skipping Samples

Unapproved fit and construction increase bulk-production risk.

Changing Design During Production

Late changes create delays and inconsistency.

Ignoring Size Grading

One approved medium does not automatically guarantee a good XS–3XL range.

Using the Wrong Branding Method

Decoration needs to match fabric and product use.

Selecting Suppliers Only by Price

The lowest quote does not automatically offer the best total value.

Ignoring Packaging Until the End

Custom packaging can require additional development and sourcing time.

No Reorder Documentation

Repeat production becomes less predictable without retained specifications.

What Actually Changes Sportswear Manufacturing Cost?

Sportswear pricing depends on multiple variables.

Cost Factor	Why It Matters
Fabric	Technical and specialty materials affect cost
GSM	Fabric consumption changes
Quantity	Influences manufacturing efficiency
Pattern complexity	More panels and operations increase labour
Zippers and trims	Hardware can materially change cost
Printing	Method, area and colours affect production
Embroidery	Stitch count affects production time
Custom labels	Adds sourcing and application
Packaging	Retail-ready presentation adds materials
Testing	Requested laboratory work adds cost
Shipping	Weight, volume and destination affect freight

This is why accurate quotations require detailed product specifications.

Sample Cost vs Bulk Cost

Sample production usually costs more per unit than bulk production.

A sample may require:

• Pattern development
• Fabric sourcing
• Artwork setup
• Logo development
• Machine setup
• Manual adjustments

Those development activities are concentrated into one or a few garments.

In bulk production, setup costs are distributed across a larger quantity.

Buyers should therefore avoid comparing the sample unit cost directly with mass-production pricing.

How Long Does Sportswear Manufacturing Take?

There is no universal production timeline.

Timing depends on:

• Product complexity
• Sample revisions
• Fabric availability
• Custom colours
• Custom trims
• Quantity
• Printing
• Testing
• Packaging

A realistic project should allow time for both:

development

and

bulk production

Trying to compress development too aggressively can increase the risk of mistakes.

What Brands Should Ask a Sportswear Manufacturer

Before selecting a supplier, ask practical questions.

Does the manufacturer support:

• Sampling?
• Fabric sourcing?
• Custom patterns?
• Size grading?
• Printing?
• Embroidery?
• Custom labels?
• Packaging?
• Low MOQ?
• Bulk production?
• Repeat orders?
• Quality control?

Also ask:

• What files are required?
• How are samples approved?
• What is the normal production process?
• How are bulk changes controlled?
• How are reorders reproduced?

Manufacturing capability should be evaluated through process, not marketing language alone.

Cross-Category Manufacturing for B2B Buyers

Some buyers operate across several product categories.

A distributor may sell:

• Sportswear
• Team uniforms
• Equestrian products
• Motorcycle apparel

A brand may begin with:

• Leggings
• Hoodies

and later expand into:

• Tracksuits
• Teamwear
• Bags
• Accessories

Cross-category manufacturing can reduce supplier fragmentation when one partner has the relevant capability.

However, each category should still follow its own technical requirements.

GHC Sportswear® supports additional B2B categories including custom wholesale sports uniforms, custom equestrian gear and custom motorbike gear.

Business Operations Matter as the Brand Scales

Manufacturing becomes more difficult as order volume and product count increase.

Growth creates more:

• SKUs
• Suppliers
• Colours
• Sizes
• Shipments
• Customer requirements

Brands therefore need operational systems around their manufacturing.

This includes:

• Product records
• Reorder control
• Supplier information
• Quality data
• Order tracking
• Packaging specifications

For the broader operational framework, read Business Operations Management.

Frequently Asked Questions About Custom Sportswear Manufacturing

What is custom sportswear manufacturing?

Custom sportswear manufacturing is the development and production of sportswear according to a buyer’s own design, fabric, fit, size, colour, branding, label and packaging requirements.

What is the difference between custom sportswear and ready-made sportswear?

Ready-made sportswear uses existing manufacturer or retailer specifications. Custom manufacturing allows the buyer to control the product specification.

What products can a sportswear manufacturer make?

Depending on capability, products may include gym shirts, tracksuits, leggings, compression wear, sports bras, hoodies, shorts, jackets, training wear and sports uniforms.

What is OEM sportswear manufacturing?

OEM manufacturing generally means producing according to the buyer’s specifications, designs or technical files.

What is ODM sportswear manufacturing?

ODM generally includes greater manufacturer involvement in product development in addition to manufacturing.

What is private label sportswear?

Private label sportswear is manufactured for sale under the buyer’s own brand identity.

Do I need a tech pack?

A detailed tech pack is strongly useful, but development can also begin from reference products, images, measurements and written specifications.

Can a manufacturer copy a physical sample?

A physical reference sample can be used as a development reference when the buyer has the right to reproduce the design. Specifications and requested modifications should still be documented.

What fabrics are commonly used in sportswear?

Common materials include polyester, polyester-spandex, nylon-spandex, mesh, interlock, jersey, fleece and other technical knitted or woven fabrics.

What does GSM mean?

GSM means grams per square metre and is used to describe fabric weight.

Is higher GSM always better?

No. The correct GSM depends on the product. Running garments may require lightweight fabric, while compression or winter products may use denser materials.

What fabric is best for leggings?

High-stretch nylon-spandex or polyester-spandex fabrics are common, but the correct fabric should also provide suitable recovery, opacity, hand feel and durability.

What is four-way stretch?

Four-way stretch describes material that stretches substantially in both primary directions of the fabric rather than mainly in one direction.

What is stretch recovery?

Stretch recovery is the material’s ability to return toward its original dimensions after being stretched.

Why does sportswear need sampling?

Sampling allows buyers to evaluate fabric, fit, measurements, construction and branding before larger quantities are produced.

What is a pre-production sample?

A pre-production sample is an approved sample intended to represent the specification before bulk manufacturing begins.

What is a size set?

A size set contains selected sizes used to review fit and grading across the size range.

Can sportswear be custom sized?

Yes. Custom measurement charts and size systems can be developed depending on project requirements.

Can a manufacturer create men’s and women’s fits?

Yes. Separate men’s, women’s and unisex patterns can be developed according to the product and target market.

Can sportswear have custom colours?

Yes. Custom colours may be developed depending on material, quantity and supplier requirements.

Can sportswear be sublimated?

Suitable polyester sportswear can use sublimation for detailed, multicolour and all-over artwork.

Can sportswear be embroidered?

Yes. Embroidery is suitable for many heavier or more structured sportswear products such as hoodies, jackets, polos, caps and tracksuits.

What branding options are available?

Options can include sublimation, screen printing, heat transfer, DTF, embroidery, silicone logos, rubber patches and woven labels.

Can I add my own labels?

Final Thoughts

Custom sportswear manufacturing is not simply the process of sewing garments.

It is the system that turns:

Design ideas into approved samples.

Approved samples into consistent production.

Production into repeatable branded products.

Brands that manage the process properly gain greater control over:

• Fabric
• Fit
• Sizing
• Performance
• Branding
• Quality
• Packaging
• Reorders

Startups benefit because development becomes more controlled.

Wholesalers benefit because products can be reproduced.

Retailers benefit because sizing and branding remain consistent.

Established sportswear brands benefit because the manufacturing system can support broader collections and larger volumes.

GHC Sportswear® supports international B2B buyers through product planning, fabric and trim sourcing, apparel sampling, surface design, controlled manufacturing, private label branding, packaging, fulfillment and repeat production.

A strong sportswear brand starts with a good product.

A scalable sportswear brand needs a manufacturing system capable of making that product consistently.
