Made from a 100% recycled polyester fabric thats incredibly soft, light and fast-drying, the Vayper is designed to be a true next-to-skin base layer, ideal for a range of high output activities. The close, athletic cut allows the Vayper to pull sweat away from the skin much more rapidly when youre working hard and the ultralight fine knit fabric retains less moisture, meaning it dries quicker. Polygeine treated fabric keeps the Vayper pong-free after multiple uses and allows you to go longer between wash cycles.

Highly effective as a cool standalone layer in milder conditions, the Vayper also fits neatly underneath midlayers and bike jerseys as part of your layering system. Despite its silky barely there feel, when worn underneath layers the fabric traps narrow pockets of still, warm air, adding extra warmth without the bulk.
