The Pace Air Tee is built for high-output activities where breathability and comfort matter most — running, fast hiking, and mountain biking in warm or humid conditions. Made from Rerun Jersey, an ultralight 115 g/m² fabric constructed from 100% recycled polyester, the tee offers a smooth, stretchy feel that moves with you without restriction. Its slim fit, flat seams, and anti-snagging knit construction keep chafing and irritation to a minimum during extended effort.
