Top 10 Gym & Sports T-Shirt Manufacturers (2026 Buyer List)

Finding gym T-shirt manufacturers is easy. Finding one that fits the product you are actually trying to build is much harder.

Some factories are strongest in fitted gym tops and stretch-based workout shirts. Others are better at lightweight running tees, moisture-wicking sports T-shirts, sublimated teamwear, or broader private label activewear programs.

Those differences matter.

A supplier that performs well with standard polyester event shirts may not be the right performance T-shirt manufacturer for a premium training line. Likewise, a factory experienced in leggings and sports bras may still need to prove that it understands shoulder mobility, underarm comfort, fabric weight, print durability, and size consistency in sports T-shirts.

This 2026 buyer list compares 10 gym and sports T-shirt manufacturers across China, the USA, and wider global production networks. It is intended for activewear brands, gymwear labels, clubs, teams, distributors, and buyers looking for OEM, private label, moisture-wicking, quick-dry, or sublimated sports T-shirts.

Quick Comparison: 10 Gym and Sports T-Shirt Manufacturers

How We Evaluated These Manufacturers

This is a buyer-focused shortlist, not a ranking based only on factory size.

We reviewed the companies according to publicly available information on their official websites, including:

• Experience with gym, sports or performance T-shirts
• Functional fabric and activewear capability
• OEM, ODM or private label support
• Printing, sublimation and branding options
• Broader product development capability
• Publicly stated production footprint
• The type of buyer or program each supplier appears best suited to

Public information can help a buyer build a shortlist, but it does not replace sampling, testing, compliance checks, factory verification or written purchase-order requirements.

A note on disclosure: this article is published by Diguan, which is also included in the list. Diguan is presented first because it is the most relevant option for running-led projects within the context of this website. Buyers should still compare suppliers independently and choose according to their own product, market and order requirements.

1. Diguan — Best for Running-Led OEM/ODM Sports T-Shirts

Diguan is a China-based OEM and ODM sportswear manufacturer focused primarily on running and cycling apparel.

That focus makes it relevant for brands developing lightweight running tees, moisture-wicking sports shirts, run club apparel, reflective training tops, breathable mesh styles, and other performance-led products.

The main advantage is product context.

A running T-shirt is not simply a regular blank tee made from polyester. Fabric weight, air permeability, underarm construction, seam placement, neckline stability, reflective logo positioning, wet cling, and fit during movement can all affect the final result.

Diguan is best suited to buyers who want to discuss these details during sampling rather than select a generic catalog shirt and add a logo.

It is also a practical option for brands that may start with T-shirts but later expand into running singlets, shorts, tights, jackets, pants, or coordinated club apparel.

Best for: Running brands, run clubs, technical sportswear startups and performance-led OEM projects.

Buyer should verify: Target GSM, fit block, moisture-management expectations, logo method, sample revisions and bulk tolerances.

2. Yotex Apparel — Best for Broader Functional Apparel Programs

Some buyers do not want a sports T-shirt supplier in isolation. They want a manufacturing partner that can support a wider functional apparel collection.

Yotex positions itself as a China-based functional apparel manufacturer providing full-package support, including material sourcing, product development, production, bulk inspection and delivery. Its publicly presented categories extend beyond T-shirts into activewear, outdoor apparel, streetwear, swimwear and related functional products.

That broader capability can be useful when a brand plans to launch performance tops alongside jackets, leggings, hoodies or other activewear categories.

The tradeoff is that a broad category range does not automatically mean the same depth in every product.

If the success of your collection depends on one highly specific performance tee, ask to see comparable samples. Check whether the supplier has already worked with the required fabric weight, fit, seam construction and logo process.

Best for: Brands developing a wider functional apparel line under one manufacturing relationship.

Buyer should verify: How much of the factory’s regular production is genuinely close to the proposed sports T-shirt.

3. Ohsure — Best for Flexible Private Label Gym T-Shirts

Ohsure presents sports T-shirts, gymwear and custom activewear as central parts of its manufacturing offer.

Its website highlights OEM, ODM and private label services, along with fabric selection, logo application, labels, hangtags, packaging and other brand-facing customization. It also shows short-sleeve, long-sleeve, slim-fit, loose-fit and sports T-shirt options.

That range makes Ohsure relevant for newer activewear brands, boutique gyms, fitness businesses and buyers who want considerable flexibility around branding.

The main risk with a broad customization menu is an unfocused brief.

“Custom gym T-shirt” can mean a fitted nylon-spandex training tee, an oversized cotton-feel workout shirt, a lightweight polyester performance top, or a full-sleeve style. Those products require different fabrics, patterns and logo methods.

Define the use case before requesting a sample.

Best for: Private label gym T-shirts, brand-heavy customization and mixed activewear collections.

Buyer should verify: Fabric composition, finished GSM, fit reference, printing compatibility and size range before sampling.

4. SANSANSUN — Best for Performance-Led Gym and Training Tops

SANSANSUN sits closer to the gym and training side of activewear manufacturing.

Its sports T-shirt offer includes performance cotton, polyester blends, moisture-wicking fabrics, cooling materials, long-sleeve shirts and technical tees intended for running, fishing and training. The company also promotes OEM, private label, wholesale and product-development services.

This makes it relevant for brands looking for a gym T-shirt manufacturer that understands fitted training tops, workout shirts, stretch-based apparel and coordinated fitness collections.

That activewear background can be useful when a tee needs to work alongside leggings, sports bras, gym shorts, compression products or training hoodies.

Still, buyers should evaluate the exact product rather than the category label.

A factory may be experienced in fitted gymwear but less suitable for a very lightweight race tee. Another may be strong in long-sleeve training shirts but need more direction on loose or oversized gym silhouettes.

Best for: Fitness brands, private label gymwear and performance-oriented training collections.

Buyer should verify: Fabric testing, stretch recovery, seam type, body fit and the supplier’s experience with the intended tee category.

5. Active Wear Productions — Best for Dry-Fit and Commercial Sports Tees

Active Wear Productions is a Hangzhou-based activewear manufacturer with a product range that includes dry-fit T-shirts, fitness tees, running tops, tanks, shorts and jackets.

Its presentation is practical and product-led. Buyers can see multiple fitness and performance styles rather than only general statements about apparel manufacturing.

That makes the company easier to shortlist for commercial gym T-shirts, branded athletic basics, dry-fit tops and wider activewear programs.

It may be particularly useful for buyers who want an existing manufacturing framework and a clear development route without turning every style into a highly experimental product.

The main question is how far the supplier can move beyond standard performance styles when a brand requires a more differentiated fit, custom fabric construction or distinctive visual identity.

Best for: Dry-fit shirts, commercial performance programs and wider activewear sourcing.

Buyer should verify: Custom pattern capability, available fabric development, sample revision process and bulk quality controls.

6. Signal Sportswear — Best for Premium Functional Apparel Programs

Signal Sportswear operates in a more technical and established manufacturing environment.

The company states that it has more than four decades of experience producing functional apparel for sports and outdoor brands. Its public manufacturing footprint includes Bangladesh, Cambodia and China, with an emphasis on end-to-end performance apparel production.

This type of supplier profile is more relevant when a sports T-shirt is part of a technically demanding or premium collection.

The buyer may care about formal development systems, performance materials, sourcing depth, quality procedures and the ability to support a larger apparel program—not only one low-cost tee.

That does not automatically make Signal the right choice for every brand.

A startup testing a small run of simple gym shirts may need a more flexible supplier. An established performance or outdoor label may place greater value on the structure and manufacturing network Signal presents.

Best for: Established sports, outdoor and premium performance brands.

Buyer should verify: Minimum order expectations, development costs, communication structure and whether the proposed order fits the company’s production model.

7. Active Apparel Group — Best for Structured Premium Activewear Development

Active Apparel Group positions itself as a manufacturer of activewear, outerwear and swimwear across performance and lifestyle markets.

The company has an Australian head office, a US office and manufacturing operations in China. It states that it owns and operates manufacturing facilities to maintain greater control over quality and consistency.

That structure can appeal to premium brands looking for more than a basic sports T-shirt factory.

Fabric development, fit technology, sourcing, production control and the ability to extend into other performance categories may all be relevant when a brand is building a long-term collection.

However, a more structured manufacturing platform may not be the natural fit for every small order.

Buyers should be realistic about their volume, commercial readiness and development expectations before approaching a supplier of this type.

Best for: Premium brands building coordinated performance and lifestyle apparel programs.

Buyer should verify: Project scale, development requirements, costing structure and fit with the company’s customer profile.

8. Lefty Production Co. — Best for USA-Based Development

Not every buyer wants to begin with offshore production.

Lefty Production Co. is a Los Angeles-based design, development and manufacturing business covering activewear, athletic wear, sportswear and athleisure. Its services are relevant to brands that value local communication, hands-on development and Made in USA production.

This can make sense for collections that sit between technical activewear and fashion.

Oversized gym T-shirts, studio-to-street tops, performance basics and brand-led athleisure styles may benefit from a development process that allows closer collaboration and faster physical review.

The tradeoff is usually cost.

A USA-based manufacturer is unlikely to compete with China or Southeast Asia purely on unit price. The value is more likely to come from proximity, development access and domestic production positioning.

Best for: US brands, local development and athleisure-adjacent sports T-shirts.

Buyer should verify: Production cost, material sourcing, achievable volume and which stages are completed locally.

9. Yinshan Sportswear — Best for Teamwear and Sublimated Sports T-Shirts

Yinshan Sportswear focuses on custom sportswear, teamwear, promotional clothing, events apparel, uniforms and fitness products.

That profile makes it especially relevant for sports T-shirt programs built around teams, clubs, races, schools, corporate events or graphic-heavy customization.

The company also presents custom sublimation T-shirts and related design and production services. Sublimation can be valuable when the artwork needs broad color coverage, player numbers, sponsor graphics or designs that extend across multiple garment panels.

However, buyers should distinguish between teamwear strength and retail activewear strength.

A team shirt may prioritize graphic clarity, color repeatability and fast reordering. A premium retail gym tee may place more emphasis on handfeel, fit refinement, seam appearance and lifestyle presentation.

Best for: Teamwear, events, clubs, promotional sports programs and sublimated T-shirts.

Buyer should verify: Sublimation color consistency, artwork setup, fabric handfeel, size repeatability and reordering procedures.

10. Aktik Sportswear — Best for Custom Dri-Fit Gym T-Shirts

Aktik speaks directly to buyers looking for custom dri-fit shirts and commercial sports T-shirt programs.

Its product offering includes moisture-wicking custom T-shirts, compression shirts, reflective raglan tees, fitted athletic tops and full-length-sleeve options. The company also presents private label and broader activewear manufacturing capabilities.

This direct product focus makes Aktik easier to evaluate than a general apparel supplier that only mentions sportswear as a minor category.

Gym tops, training shirts, dri-fit event tees and branded athletic basics all fit naturally within this type of offer.

As with any catalog-driven supplier, buyers should use the catalog as a starting point rather than assume the displayed sample already meets their brand requirements.

Best for: Custom dri-fit T-shirts, gym performance tops and commercial private label programs.

Buyer should verify: Finished fabric specifications, pattern customization, logo durability, sample approval and bulk consistency.

Gym T-Shirt Manufacturers vs Sports T-Shirt Manufacturers: What Is the Difference?

The two terms overlap, but they do not always describe the same supplier strength.

A gym T-shirt manufacturer is usually more focused on fitness tees, training shirts, oversized workout tops, fitted performance styles and gym-lifestyle products. Fabric handfeel, stretch recovery, body shape, logo appearance and coordination with other gymwear categories often matter.

A sports T-shirt manufacturer may cover a wider range, including:

• Running shirts
• Teamwear
• Race and event tees
• Club apparel
• Dri-fit shirts
• Sublimated tops
• General performance T-shirts

The correct choice depends on where the product will be used and how it will be sold.

A fitness brand launching fitted or oversized workout tops may benefit from a gymwear-focused supplier. A buyer serving running clubs, teams and events may need a broader sports T-shirt factory with stronger sublimation, quick-dry and reorder capabilities.

Do not choose according to the label alone. Ask to see products that are genuinely similar to your intended style.

What to Check in a Performance T-Shirt Manufacturer

A performance T-shirt manufacturer should understand more than sewing and logo placement.

For wash-related size stability, buyers may also reference ISO 5077 when defining how dimensional change should be evaluated after washing and drying.

Before shortlisting a factory, ask for evidence in five areas.

Comparable Product Experience

Request samples or production photos close to your intended use case.

A lightweight running tee, fitted gym shirt, full-sleeve training top and sublimated team shirt should not all be treated as the same product.

Fabric Specifications

“Quick dry” and “moisture-wicking” are often used too loosely.

When moisture management is a purchase requirement, buyers can ask whether the fabric has been evaluated using a recognized method such as AATCC TM195 for liquid moisture management properties.

Ask for the fabric composition, GSM, knit construction, stretch level, shrinkage expectation, colorfastness and any available performance test information.

Fit and Size Grading

Confirm whether the factory will use its standard block, modify an existing pattern or develop a new one.

The shoulder, chest, sleeve opening, armhole, body length and hem shape should support the intended movement and market.

Logo Compatibility

Screen printing, heat transfer, sublimation, reflective transfer and embroidery behave differently on lightweight performance fabrics.

The logo method should be selected after the fabric is confirmed—not before.

Bulk Repeatability

Ask how the factory controls measurements, fabric shade, logo position, stitching, packing and approved-sample consistency during bulk production.

A good sample is useful. A repeatable bulk process is what the buyer is actually paying for.

How to Shortlist a Sports T-Shirt Factory Before Sending an RFQ

Do not send the same vague message to ten suppliers and choose the lowest number.

First, narrow the list according to the actual product.

A useful first-round shortlist may include:

• One factory with strong experience in the exact tee category
• One broader activewear manufacturer that can support future expansion
• One alternative supplier with a different country, cost or production structure

Then ask each factory the same core questions:

1. Have you produced a similar gym or sports T-shirt?
2. Can you source the required fabric composition and GSM?
3. Can you modify the fit and size grading?
4. Which logo method works best with the proposed fabric?
5. What does the sample process include?
6. How will the approved sample be controlled during bulk production?

These questions make suppliers easier to compare without turning this article into a full manufacturing quote guide.

FAQ

Can these manufacturers make full-sleeve gym T-shirts?

Many of them can, but a full-sleeve gym T-shirt should be sampled as its own style.

Buyers should check sleeve stretch, underarm mobility, elbow comfort, cuff or open-hem construction, heat buildup, sleeve length and size grading. Extending the sleeve of an existing short-sleeve pattern is not always enough.

Ask the manufacturer to show previous full-sleeve gym or training shirts made with a similar fabric and fit.

Can sports T-shirt manufacturers make private label gym T-shirts?

Yes. Many sports T-shirt manufacturers offer private label services such as custom logos, neck labels, care labels, hangtags, packaging, custom colors and size grading.

However, private label can mean different things.

Some factories apply branding to existing styles. Others can develop custom patterns, fabrics and construction. Confirm which level of customization is included before requesting a quote.

What makes a moisture-wicking sports T-shirt manufacturer different from a basic T-shirt factory?

A moisture-wicking sports T-shirt manufacturer should understand lightweight synthetic knits, sweat movement, drying behavior, stretch, seam comfort and logo compatibility.

A basic T-shirt factory may be highly capable with cotton jersey but less experienced with mesh panels, polyester-spandex fabric, reflective transfers or lightweight performance construction.

The safest approach is to test the actual fabric and sample rather than rely only on a “moisture-wicking” description.

Are sports T-shirt manufacturers the same as sports T-shirt brands?

No.

A sports T-shirt brand markets and sells finished products. A manufacturer develops or produces those products for brands, retailers, teams, clubs and distributors.

B2B buyers building their own collection normally need a factory, OEM manufacturer, private label supplier or product-development partner—not another retail sports brand.

What should a buyer include in the first enquiry?

The first enquiry should state the product type, intended use, fabric direction, fit, order quantity, target size range, logo method, packaging needs and delivery market.

A tech pack, reference sample or clearly marked product image will usually make the discussion more useful.

Final Thoughts

There is no single best gym or sports T-shirt manufacturer for every brand.

The right supplier depends on whether the product is a lightweight running tee, a fitted gym top, a full-sleeve training shirt, a sublimated team jersey, a private label athletic basic or part of a wider performance collection.

Use the list to build a shortlist—not to skip the evaluation process.

Compare relevant samples. Confirm the fabric. Test the fit. Agree on the logo method. Put measurement and quality requirements in writing. Then assess which factory communicates clearly enough to repeat the approved result in bulk.

For brands building running-led sports T-shirts, club tops or broader performance apparel, Diguan can support fabric selection, fit development, custom branding, sampling and OEM/ODM bulk production.
