Gildan G420 - Unisex Performance® T-Shirt - White

The Gildan G420 is a 5 oz 100% polyester performance tee with AquaFX moisture-wicking and Freshcare anti-microbial finish, built for athletic, event, and spirit-wear programs where the garment needs to wick sweat and resist odour. It is the polyester substrate that changes the decoration playbook: because it is 100% polyester, it is one of the few blank tees in the wholesale channel that takes full-colour sublimation, which makes it the default for all-over print athletic jerseys, full-colour event tees, and any program where sublimation is the decoration method. The Safety Green colourway is ANSI/ISEA 107 hi-vis compliant for workwear programs.

The decoration strategy on the G420 starts with sublimation, which is the method this substrate is built for. White and light-coloured G420 tees take full-colour sublimation with vibrant, permanent, wash-fast results that cotton blanks cannot achieve. For DTF transfers, the polyester surface bonds with transfer adhesives at standard heat-press settings, and the snag-resistant finish keeps the film seated cleanly. For screen printing, plastisol prints on the polyester face, but the 100% poly content carries high dye migration risk on all coloured garments. Use a poly-blocking plastisol or low-bleed ink system and cure at the minimum effective temperature. Water-based and discharge inks do not work on 100% polyester. For embroidery, the 5 oz performance jersey is lighter than a cotton tee, so use a tear-away or cut-away backing appropriate to the design size and stitch count. For vinyl/HTV, the polyester surface holds vinyl at lower press temperatures than cotton; follow the film manufacturer's polyester-specific settings.

The G420 competes with the A4 N3142 Cooling Performance Tee and the Sport-Tek ST350 PosiCharge Competitor in the wholesale performance tee market. The G420 is the value option in this class, priced below both competitors while offering the same 100% polyester substrate for sublimation and moisture-wicking. For programs that need a cotton hand instead of a polyester performance feel, route to a cotton or cotton-blend blank like the Gildan G500 or the Hanes 4980. TheClothingSpace stocks the G420 at wholesale pricing with bulk discounts that increase as case and unit quantities rise, among the lowest prices online for this style, with fast US shipping on stocked colours.
