Sports Clothing Manufacturers for Growing Activewear Brands

A running top, gym shirt and a tennis polo can all look similar hung on a rail, but users demand very distinct performance from each product. For brands in the market for sports clothing manufacturers, the task is not just about the ability of a factory to produce clothing.

Start With the Sport

Training may require very different things to the running. Typically running clothing will prefer to be light weight, wick sweat away, breathability and freedom to move around your shoulders and arms. Training clothing may prefer to be not as light weight, more stretchable, thicker uppers and reinforced areas, with many more stitches…

Different product specifications are raised for tennis, cycling, football and outdoor training. Tennis clothing requires freedom of movement across the shoulder, but cycling kit seems to have tight fit patterns and well placed seams. For team sports performance in jersey fabrics by lightweight, chequered colors, graphics and long life washings are specific requirements.

Accordingly, designers for experienced brands should begin from the sport and the movement of the athlete before selecting fabrics or details of construction. This allows brands to make items around the real use of the sports garment, rather than using every sport garments as basic T-shirt.

Fabric Controls Performance

Polyester is still one of the most popular fibers for performance apparel. Textile Exchange states that polyester is strong, durable, crease resistant, and fast drying. The group also lists nylon as another popular performance fiber for activewear, swimwear and other technical apparel.

Nylon is a different blend of durability and stretch. When added to elastane or spandex, brands will blend nylon with it to improve the stretch and recovery for leggings, sports bras, fitted tops or training garments. Textile Exchange points out that durability and stretch in nylon are two reasons its a popular choice for activewear.

At the same time, fabric weight affects the wearability and performance of a garment. For instance, PRP Apparel provides a list of nylon/spandex, polyester/spandex, and recycled polyester combinations for various sportswear items, ranging from 150–280 GSM. ( PRP Apparel) The producer says that compression leggings usually require heavier-weight fabrics than athletic tops.

Construction Changes the Experience

In addition to comfort for long training sessions flat lock seams can be beneficial, since it lies close to the surface of fabric, and the seam itself doesn‘t cause much friction between skin and fabric. PRP Apparel provides flat lock construction (done in their own production) for all their compression leggings, sports bras and fitted training tops but they also provide bonded seams for some selected products.

Additional fabric in the gussets allows for greater range of motion in leggings, training shorts, etc. Also, reinforcement can allow the product to hold up against consistent shear and tensile force and seams placed precisely can decrease the number of premature chafing points during running, lifting, stretching or cycling.

Use construction details relevant to the sport rather than including such features to imply technical superiority. A lightweight running shirt does not require the same construction techniques as a compression legging or a bulky training short.

Fit Should Follow Movement

In order for compression clothing to work effectively the pattern development has to be in tandem with that of the stretch of the fabric. It is the job of the producers to know how the fabric will behave when the athlete spars, squats, stretches, runs or lifts.

Relaxed sportswear is another story. For example one loose training T shirt must be roomy enough for any movement but not so much fabric hangs on the body. Larger athletic cut items also require correct shoulder and sleeve width to maintain the proper shape when moving.

Sampling allow brands to discover these issues through the sampling process rather than on bulk production. Currently Canting activewear indicate that there is a minimum of 50 piece per style and color, from 7 to 12 days to develop a sample and from 30 to 45 days to produce on bulk. Furthermore the list indicates that monthly capacity is over 150 000 pieces in both finished cut-and-sew activewear and seamless activewear

Testing Goes Beyond Appearance

A piece of sports kit may look spot on during a fitting but still be unsuitable when used repeatedly. Companies should link testing to the function of the kit, rather than only optics.

The American Association of Textile Chemists and Colorists (AATCC) has test methods for colorfastness to perspiration, laundering, water, rubbing and light. Additional standards account for dimensional change, abrasion, absorbency, liquid moisturesharing, wicking and the textile drying performance.

Moisture management is also especially important in performance apparel. AATCC recognizes TM195 for liquid moisture management, TM197 for vertical wicking, TM198 for horizontal wicking and TM199 and 200 for the textile‘s drying performance. In 2025 they also recognizes TM217, in which image analysis is used to determine the vertical and horizontal movement of the moisture.

Color performance is important as athletes regularly wash the sportswear. Because of this, sportswear makers can use numerous AATCC approaches to diagnose resistance to moisture, water, laundry, rubbing and sunlight instead of directly using any visual monitoring

Manufacturing Capability Matters

Particularly certain T-shirts or sportswear manufacturers have expertise in producing more professional T-shirts for example with functionality there are more sophisticated requirements: stretchy fabrics, compression construction, flatlock seams, sublimation, mesh panels and technical finishes.

This is a good real example from the way. PRP Apparel manufactures a style based minimum of 50 pieces, 12– 15days for samples, 35– 45 days for bulk production. Its sportswear makes flatlock seaming, sublimation printing, Pantone matched dyeing, bonded seaming and many boost fabric mix.

Another key point is order configuration. A factory can have a low MOQ but work out that MOQ for each style or color separately. Brands should inquire about whether the quoted MOQ is for the complete order, for each style or for each individual colorway. PRP Apparel for example, quotes 50 pieces per style and clarifies that one colorway is considered a full style order.

Ask the Right Questions

Brands have to have a product brief prepared before contacting a manufacturer. Indicate the sport, customer profile, fiber content, gsm, fit, sizing, shades, decoration, quantity, performance needs, etc.

Follow up on fabric sourcing, pattern making and development, sample tweaking, testing options, production volumes, quality control, packaging, etc. For brands that have a tech pack, reference garment or product sketch, the manufacturer gets a lot more accurate and precise information to work from.

Ask for a physical sample before placing your order (if possible). With the physical sample in hand, check the sample against your design and measurement specs as well as the fabric fit/behavior, construction, decoration, feel and freedom of movement. A physical sample provides a tangible reference for everyone before the factory begins cutting fabric.

From Sample to Bulk Production

After the sample has been approved by the buyer, the manufacturer proceeds with sourcing fabric, pattern maker, cutting, sewing, decorating, finishing, inspection, and packing.

Rather than a basic visual check by quality teams, bulk garments should be cross referenced with the sample approved by the buyer. The quality inspector can examine the dimensions, sewing, fabric, color, print position, label & trim and overall construction before despatch.

JiuvelWear, a division of Dongguan Jiuzuo Clothing Co., Ltd, provides clothing manufacturing solutions for brands; from fabric sourcing, sampling, production, QC and inspection. For sportswear projects, the team can develop a project based on a product idea, a reference garment, or a tech spec toward a finished sample.

The Right Manufacturer Starts With Product Understanding

In the final analysis, selection of sports clothing manufacturers should not depend primarily on price or MOQ. Brands should query whether the manufacturer:.

Running tops call for different manufacturing decisions than compression leggings. Tennis wear call for different movement considerations than gym hoodies. Team jerseys call for different decoration and color-control decisions from training shirts.

As brands grow, they will become more valuable if they find a manufacturing partner that truly understands these variations. An appropriate manufacturing partner will assist in linking fabric selection, pattern creation, construction, testing and bulk manufacturing into one workable product-development system.
