Whether layered deep for a frigid day of backcountry skiing or worn alone on a warm-weather training mission, the Aero Long Sleeve Crewe is an ultralight merino tee designed for high-output, high-performance outings. Updated with an improved fit and designed with Icebreaker’s lightest-weight merino jersey fabric blended with nylon for added durability, the Aero breathes extremely well, dries in a flash and resists odors during extended travel and long days outside. Flatlock stitching and forward-set side seams prevent chafing when you’re on the move.
