The Basic Performance-T is more comfortable than other well-known sublimation shirts because the performance fabric has been engineered to keep you cool. This fabric wicks moisture away from the body while other shirts actually trap moisture. Built in anti-microbial and anti-stain features is an added bonus. 6.1 oz. Vapor is made with Intera yarn, a fabric which keeps you warmer or cooler, and resists soil, odor and bacteria. Intera is not a coating, but part of the fiber of the yarn, and does not wash out.
