4.5 oz. 100% polyester jersey knit. AquaFX moisture-wicking. FreshCare anti-microbial. Youth sizes XS through XL. Multiple colors.
The Gildan G420B is the youth version of the popular G420 Performance Tee, delivering the same moisture-wicking 100% polyester construction in a youth-sized format for school athletic programs, youth sports leagues, summer camps, and any application where young athletes need a real performance shirt rather than a standard cotton tee. The 4.5-ounce 100% polyester jersey is genuinely lightweight and breathable, which keeps kids comfortable during high-output activity in warm conditions.
AquaFX moisture-wicking technology pulls sweat away from the skin during active play, and FreshCare anti-microbial properties extend the wearable life of the garment between washes by limiting odor-causing bacteria growth. Both features deliver real practical benefits for youth sports programs where kids generate plenty of sweat and parents handle the laundry. The 100% polyester construction makes the G420B fully compatible with sublimation printing for programs that want vibrant team colors or all-over designs.
For the adult version of the same Performance Tee, check the Gildan G420 Adult Performance T-Shirt for mixed-age team programs that need consistent fabric across youth and adult sizing. For a youth performance hoodie in the same active-program category, the Sport-Tek YST255 Youth Sport-Wick Fleece Pullover Hoodie covers the layering piece. For a youth cotton tee at a lower price point when performance fabric is not required, the Gildan 64000B Youth Softstyle T-Shirt offers a softer hand feel for casual programs.
What is AquaFX moisture-wicking?
AquaFX is Gildan's branded moisture-wicking technology. The 100% polyester construction is engineered to move sweat away from the skin and dry quickly, keeping young athletes comfortable during active use. It performs comparably to other branded wicking technologies in the wholesale youth performance category.
Is the G420B good for sublimation printing?
Yes. The 100% polyester construction is fully compatible with sublimation printing, which requires high polyester content for vibrant, durable color transfer. The G420B is one of the more accessible sublimation blanks in youth sizing, making it practical for programs that want all-over color decoration on a budget-friendly youth performance tee.
