Technical performance mixes with urban sensibility in this airy crew. Worn alone, it provides 50+ UPF sun protection, superior stretch and a cool, drying airflow. Paired with another layer, it wicks moisture and adds some warmth when temperatures drop. Made with our stretchiest Capilene(R) 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 angled side seams for layering comfort. Made of 4.6-oz 94% polyester/6% spandex jersey with 50+ UPF sun protection and Polygiene(R) permanent odor control. Fabric is bluesign(R) approved.
