100% polyester PosiCharge moisture-wicking fabric. Racerback silhouette. Sizes XS through 4XL. Multiple colors.
The LST356 is the women's racerback version of Sport-Tek's Competitor tank family — a performance tank built for active programs where moisture management and color retention through a full season of washing both matter. PosiCharge technology wicks sweat away from the body and locks color so team colors and any heat transfer or screen-printed decoration stay sharp through repeated laundering.
The racerback construction gives it unrestricted shoulder movement for athletics, yoga, and high-output training, while keeping the silhouette clean and fitted enough for lifestyle wear beyond the gym. The 100% polyester fabric dries quickly and resists the odor retention that cotton-dominant fabrics can develop in active use. For programs outfitting a women's team, athletic staff, or fitness-focused lifestyle brand, the LST356 is a reliable, practical option across a wide size range.
For the men's and unisex Competitor tank in the same PosiCharge family, the Sport-Tek ST446 Club Track Tank covers unisex sizing. For a women's PosiCharge performance tee to pair with the LST356 for a coordinated set, the Sport-Tek LST800 Ladies Jacket is worth checking for layering options. For a cotton-feel women's tank at a lower price point, the Tultex 190 Women's Poly-Rich Racerback Tank Top is a natural comparison.
What is PosiCharge technology?
PosiCharge is Sport-Tek's color-lock and moisture-wicking system. It wicks sweat away from the body during active use and prevents the dye from fading or bleeding through washing, which keeps team colors and decoration looking sharp through a full season.
Is the LST356 suitable for sublimation printing?
The 100% polyester construction makes it fully compatible with sublimation printing, which produces vibrant, all-over color on polyester fabrics. It also works well for heat transfer and screen printing with inks formulated for synthetic fabrics.
What sizes are available?
