Gildan G427 - Unisex Performance® Sleeveless T-Shirt - Black

The Gildan G427 is a 4.5 oz 100% polyester performance sleeveless tee with AquaFX moisture-wicking and Freshcare anti-microbial finish, built for gym, running, and team training programs where the garment has to move sweat and resist odour across repeated wear cycles. The polyester substrate sets the decoration playbook: because it is 100% polyester, the G427 takes full-colour sublimation, which makes it the default sleeveless blank for all-over print athletic looks and full-colour fitness merch. The cut runs as a true sleeveless tee with a finished armhole rather than a deep-cut muscle tank, so the print field stays close to a standard tee width even though the sleeves are gone.

Sublimation leads on this substrate. White and light G427 tees take full-colour sublimation with vibrant, permanent, wash-fast results that no cotton sleeveless blank can match, which is why fitness brands route their poly sleeveless runs here. For DTF transfers, the polyester surface bonds with transfer adhesive at standard heat-press settings, and the snag-resistant finish keeps the film seated. The sleeveless cut does change press registration: the double-needle armhole binding raises the fabric at the shoulder, so keep large left-chest and full-front placements clear of the binding seam to avoid an uneven press. For screen printing, plastisol prints on the polyester face, but 100% poly carries high dye migration risk on every coloured garment. Use a poly-blocking or low-bleed ink system and cure at the minimum effective temperature, and flash-test the Safety Green hi-vis base before a production run because hi-vis dyes migrate aggressively. Water-based and discharge inks do not work on 100% polyester. For embroidery, the 4.5 oz jersey is light, so back left-chest and crest placements with a cut-away stabiliser to stop puckering. Vinyl/HTV holds at lower press temperatures than cotton; follow the film maker's polyester settings.

The G427 is the sleeveless companion to the short-sleeve Gildan G420 Performance tee in the same AquaFX poly fabric, so a program can run matching sleeved and sleeveless pieces with consistent dye behaviour across both. For a cotton sleeveless hand instead of a polyester performance feel, route to the Gildan G520 100% cotton tank; for a tri-blend athletic drape, route to the NL3633 tri-blend tank.
