Moabs Porcupine Rim in late May - the descents are always spectacular, but the heat can get intense. Keep yourself cool with this airy, forgiving tee. Worn alone it 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 and angled side seams for layering comfort. Made of 4.6-oz 94% polyester/6% spandex jersey, with 50+ UPF sun protection and Polygiene permanent odor control. Fabric is bluesign approved.
