Built for high-output activities like running, fast hiking, and mountain biking, this long-sleeve tee uses Houdini's Rerun Jersey — an ultralight, stretchy fabric knitted from 100% recycled polyester that dries quickly and resists snagging. The slim athletic fit moves with the body without restriction, while flat seams are strategically positioned to reduce chafing during extended sessions. At just 115 g/m², it keeps you cool in warm or humid conditions and is fully recyclable at end of life.
