This Gameness Spirit Animal Short Sleeve Rash Guard is made from 92% polyester and 8% Spandex for durability and flexibility. Approved for black belt nogi competition, it sports Gameness branding and the iconic dog logo on the sleeves. The back displays the motto: “Gameness means that neither fatigue nor pain will cause the fighter to lose their enthusiasm for the fight.” This rash guard is not a compression fit, so size down for a snugger feel.
