Hit your stride with moisture wicking and thermoregulation for the ultimate in seamless comfort even during your sweatiest cool-weather activities. Featured on Outside's List of The Best Women's Baselayers of 2023.

Extended workouts call for complete comfort and our seamless crew hits that stride due to a textured knitting process that sheds seams, increasing range and preventing chafe. Intended as a next-to-skin layer for running, biking, skiing or any outdoor exercise, the extremely athletic layer harnesses poly knit material to wick moisture, regulate temperature and layer without friction. Pinecone mesh zones increase breathability during high output activities or intervals.
