Built to move. Made to last. This long-sleeve base layer is designed for all-day wear in changing conditions. Made from a durable blend of nylon, polyester, and spandex, it delivers stretch, breathability, and a smooth second-skin feel that moves with you. The lightweight fabric helps regulate temperature and manage moisture, while integrated thumb holes keep sleeves in place and make layering easy. Comfortable enough to wear on its own, technical enough to wear under anything.
