On a warm-weather hike or a long travel day, this long sleeve tee keeps you comfortable with its ultralight 125 g/m² Cool-Lite™ fabric. The blend of 60% Merino wool and 40% Tencel™ Lyocell wicks moisture, dries quickly, and resists odour naturally, so you stay fresh from trailhead to town. Offset shoulder seams prevent pack rub, while flatlock seams reduce chafing during active movement.
