Jerzees 21ML - Unisex DRI-POWER® SPORT Long-Sleeve T-Shirt - White

The Jerzees 21ML Dri-Power Sport Long-Sleeve T-Shirt is the long-sleeve version of the 5.3 oz 100% polyester 21M performance blank, built for sublimation programs, cold-weather team athletic uniforms, and any decorated application where moisture management runs alongside long-sleeve coverage. The 100% polyester jersey carries Jerzees' Dri-Power moisture-wicking across the full fabric, pulling sweat off the skin during activity and pushing it to the surface to evaporate, which keeps the wearer drier through practice and outdoor events than a cotton or cotton-blend substrate would. Antimicrobial treatment is built into the fibre to limit odor-causing bacteria between wash cycles, a real factor on team garments worn across multiple sessions before laundering. The long-sleeve cut adds forearm and cuff print real estate the short-sleeve 21M does not have, opening sleeve-stripe, forearm sponsor, and wraparound graphic placements common on athletic and event programs. Construction matches the performance spec: seamless body, seamed 1x1 rib collar with double-needle coverstitching on the front neck, quarter-turned to eliminate the center crease, shoulder-to-shoulder taping, rib cuffs with concealed seams, and a tearaway label for custom neck-label programs. Available in 9 colours including White, Black, J Navy, Royal, and High Viz Safety colours, in S through 3XL.

Because the Jerzees 21ML 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 21ML produces all-over vivid full-colour prints with no hand feel, no cracking, and no added weight on the garment face, and the long-sleeve panel lets the graphic run down the sleeve and onto the cuff in a single dye pass. This makes it the correct substrate for spirit-wear programs, cross-country and outdoor-event shirts, and sublimated team uniforms where the art extends past the standard chest print area. DTF transfer is the most practical route for programs printing the same art across multiple colourways without 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 sit 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. Sleeve printing on a long-sleeve blank needs a sleeve platen, so confirm your platen setup before quoting forearm placements. DTG is limited because the 100% polyester body provides minimal fibre for pretreat adhesion and produces muted results against a cotton-content substrate. Vinyl and HTV press at low temperature, since 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 21ML: route all-over and sleeve graphic work to sublimation, which is the primary decoration method for this blank across all 9 colours. DTF is the correct route for multi-colour programs without sublimation equipment, particularly on High Viz Safety Green and Safety Orange 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.
