Warm weather hikes and backpacking trips just got a whole lot more comfortable with the Mountain Hardwear Men's CoolHiker T Shirt. This performance tee features a quick drying, moisture wicking DryTouch Jersey for all day comfort in hot and sticky conditions. Cool Q Zero panels instantly chill sweaty back and underarm areas with a sweat activated cooling agent. Flatlock seams conform to your every move when you're hiking, and a UPF 25 rating ensures your upper body stays protected from harmful UV rays. An antimicrobial treatment resists funky odor resulting from reuse and long distance wear.
