High mileage isn’t just your route plan, it’s what you'll get out of this technical tee. Built for strenuous hikes and hard efforts, the Sunna moves moisture away from the body to keep you cooler in hot conditions. Lightweight, stretchy fabric stays put on steep scrambles and traverses, and the pack-compatible length keeps you covered however long you’re out there. More styles include the Sunna Crew Shirt LS , Sunna Hoody , and Sunna Tank .
