Performance Knit
Poly-spandex blend built to wick moisture and stretch under load. Compatible with DTF only when the transfer is engineered for stretch.
Short version, straight from the floor.
Performance knit is the family of stretchy, moisture-wicking fabrics used in athletic wear, gym apparel, and modern uniform lines. Almost always a polyester-spandex blend, typically 88/12 or 92/8, sometimes with a small percentage of nylon or elastane. The knit structure is engineered to move sweat away from skin and to snap back into shape after stretching, which matters for athletes, workers, and anyone whose body is going to bend inside the shirt.
Assuming a performance polo prints like a standard poly polo. Performance polos have spandex in them. That spandex changes the press dwell, the dye migration behavior, and the transfer chemistry required. Every performance polo on our site has its own recipe. Do not run the same job you would run on a Port Authority K500.
Skipping the wash test on a new performance-knit SKU. Every stretch-fabric manufacturer tunes the knit and the dye slightly differently. Before running a 200-piece order on a new performance-knit blank, order a swatch or a single sample. Wash it three times. That test is the difference between shipping and reprinting.
Pressing at cotton or blend temperatures. 315 F on a performance knit gives you migration, knit deformation, and hand-feel loss. Low-temp DTF at 275 F is the working answer. If your press cannot hold a stable 275, this is not a job for your shop.

Performance knit is the family of stretchy, moisture-wicking fabrics used in athletic wear, gym apparel, and modern uniform lines.

For DTF, performance knit combines the two hardest things to print on. It is polyester, so dye migration is a real threat. It is stretch, so a standard rigid DTF cracks the first time the wearer flexes. The right answer is a stretch DTF built with a flexible adhesive and a poly-blocker white ink layer. When those two properties are correctly combined, a performance-knit tee accepts DTF and holds it for 40-plus wash cycles even under gym use.
The other consideration is the press. Performance knit fabrics run thin, usually 3.5 to 4.5 oz per square yard, and the polyester dye behavior means we cannot press at cotton temperatures. Low-temperature DTF at 265 to 285 F with a light-firm pressure and 8 to 10 seconds of dwell is the working recipe. Every performance-knit product on our site has this recipe on the page.
Where this fabric earns its price is athletic teams, corporate performance polo programs, gym-wear brands, and outdoor crews. The customer chooses performance knit because they need the moisture management. The customer choosing performance knit is not choosing hand feel; they are choosing behavior on a body under work.
The numbers we look at before quoting a job.
Every fabric on this site carries the same profile. Composition, weight range, hand feel, three decoration suitability scores, wash durability, dye migration risk, press ceiling, and how it moves after the first wash. If a field is missing on a competitor product page, it is missing because they never tested it.
Decoration suitability
Requires stretch DTF plus poly-blocker white ink. Standard DTF cracks and migrates. Right formula, this fabric holds a print well.
Plastisol on performance knit is a gamble. Stretch under wear causes cracking. Reserved for volume runs with a stretch additive in the ink.
Small logos work. Dense stitch counts distort the stretch knit and lock the fabric out of its natural movement.

Where this fabric is the wrong call.
Refusing the wrong sale is the most credible thing we do. If your job lives inside one of these edges, we route you to what actually works.
Standard rigid DTF.
A standard DTF applied to a performance-knit tee will crack on the first stretch, migrate on the first wash, or both. If you are ordering DTF for performance apparel and you did not confirm stretch-formula plus poly-blocker, that is the moment to call us.

Performance knit reads athletic on a hanger. Boutique fashion customers wanting soft, natural-fiber hand feel are not the buyer for a wicking poly-spandex tee. Match the fabric to the shelf.
Go here instead: Tri-Blend for retail-fashionFauxbroidery.
Fauxbroidery relies on a rigid stitched-look transfer that sits stable on the fabric. On a stretch performance knit, the stitched illusion breaks the first time the wearer flexes. Fauxbroidery lives on cotton, blends, and fleece, not on stretch knits.

Stretch DTF with poly-blocker is not an add-on. It is the only formula we ship for athletic and performance apparel. Order the transfer, we ship the right chemistry by default.
