Light highly breathable Airius fabric in a tee with sleeves reduce solar gain & pack chafe.

This T-shirt turns sweat into air-conditioning you'll appreciate when the pace picks up. Its puzzle-shaped Airius fibers (50% polyester 44% EVOH and 6% nylon) quickly wick perspiration to keep you dry but retain just enough moisture to produce a cooling effect as you move. The low-profile crew neck and flat seams reduce chafe under pack straps; soft snag-resistant fabric has a sun-activated ceramic component that kills odor. Reflective heat-transfer logo. Slim fit still allows for plenty of airflow. Slim fit.
