From hot-weather training to high-intensity workouts, ultralight Tempic(TM) fabric delivers cooling comfort and performance. 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(TM) 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. The UPF 50+ rating sheds high-elevation rays and flatlock seams layer smoothly under a wind- or rainshell in bursts of unexpected weather.
