Inspired by the mountain athletes we see chasing their goals on the trails, in the gym and in the high peaks around our hometown, we created our lightest-weight tech tee to bring performance and comfort to the full range of these pursuits. Ultralight, breathable Tempic™ fabric uses a honeycomb design that instantly evaporates sweat and resists odors, feeling cool and smooth even in rising temperatures. An athletic fit leaves plenty of room to move. It sheds high-elevation solar rays and offers flatlock seams that layer smoothly under a wind- or rainshell in bursts of unexpected weather.
