Everything a t-shirt should do, but with added cover- age, far less weight, and maximum breathability. Designed to wick sweat fast, we’ve worked with a dual fabric construction on this Hot Weather Tee, going for our impossibly light open-weave SPACE3D mesh on the torso and a slightly more protective closed fabric to provide UPF 50 protection against the sun’s UV rays on the sleeves, shoulders and upper back.
