Run in it, surf in it, or layer it with a lightweight shell - live in it. Worn alone, this crew provides 50+ UPF sun protection, superior stretch and a cool, drying airflow. Paired with another layer, it wicks moisture and adds warmth when temperatures drop. Made with our stretchiest Capilene® performance baselayer fabric, this shirt breathes and dries in a flash. With a tuckable length, soft self-fabric crewneck, offset shoulder seams to reduce chafing beneath pack straps, thumb loops for secure hand coverage and offset side seams. Made of 4.6-oz 94% polyester/6% spandex jersey, with Polygiene® permanent odor control. Fabric is bluesign® approved.
