Hike, climb or scramble in comfort in this adidas shirt. AEROREADY manages moisture to keep you feeling dry and comfortable as you move, making it an excellent layer under a waterproof jacket or as a standalone piece. Designed for wearing a backpack, the tee has comfortable shoulder seams to reduce chafing under straps, and a slightly longer back hem keeps you covered as you twist, bend and reach. Underarm gussets give you a wider arm range as you climb.
