The Pace Air Tee is built for high-output activities where breathability and freedom of movement matter. Constructed from Rerun Jersey — a superfine, ultralight fabric made from 100% recycled polyester — it wicks moisture quickly and resists snagging during dynamic movement. The slim fit and flat-seam construction work together to eliminate chafing, keeping the tee out of the way whether you're on a trail run or a fast-paced hike.
