Jerzees 21M - Unisex DRI-POWER® SPORT T-Shirt - True Red

The Jerzees 21M Dri-Power Sport T-Shirt is a 5.3 oz 100% polyester performance blank built for sublimation programs, team athletic uniforms, and any decorated application where moisture management and odor control are part of the garment specification. The 100% polyester construction runs Jerzees' Dri-Power moisture-wicking technology across the full fabric, pulling sweat off the skin during athletic activity and pushing it to the surface to evaporate, keeping the wearer drier longer than a cotton or cotton-blend substrate. Antimicrobial treatment is built into the fabric to limit odor-causing bacteria growth between wash cycles, which matters on team garments worn through practice schedules before laundering. The seamless body, seamed 1x1 rib collar, and double-needle coverstitching on the front neck give the 21M a construction profile consistent with team uniforms and event shirts at a unit cost that holds up on larger runs. The tearaway label keeps the inside of the neck clean for custom neck-label programs common on sublimated team apparel. Available in 12 colours including White, Black, and Safety colours, S through 3XL.

Because the Jerzees 21M is 100% polyester, it opens the full sublimation method across every colour in the range, not just white. Disperse dyes bond into polyester fibres on a molecular level, so sublimation on the 21M produces all-over vivid full-colour prints with no hand feel, no cracking, and no added weight on the garment face. This makes it the correct substrate choice for spirit wear programs, run-event shirts, and sublimated team uniforms where the graphic extends past the standard print area. DTF transfer is the most practical route for programs printing the same art across multiple colourways without investing in sublimation setup: the transfer bonds to the 100% polyester face without migration risk from dye in the fabric, and the tearaway label supports a concurrent custom neck-label press. For screen printing with plastisol, the 100% polyester composition carries the highest dye migration risk in the performance tee category. Low-bleed, low-migration plastisol ink is mandatory on any colour other than white, cure temperature must be set at the absolute lowest effective range for the ink system, and a poly-blocking underbase is required under any light or bright ink on coloured grounds. DTG printing is limited on the 21M because the 100% polyester body provides minimal fibre for pre-treat adhesion and produces muted results compared to a cotton-content substrate. Vinyl and HTV press at low temperature; polyester scorches quickly so monitor the press closely on the first application. Water-based and discharge inks are not viable on this blank.

For team and event programs on the Jerzees 21M: route all-over graphic work to sublimation, which is the primary decoration method for this blank across all 12 colours. DTF is the correct route for multi-colour programs without sublimation equipment, particularly on Safety Orange and Safety Green where dye migration risk under plastisol is highest. If screen printing with plastisol, specify low-bleed ink in writing with your ink supplier and set your dryer at the lowest effective cure temperature before the full run.
