From snowshoeing and skiing to summer glacier hiking, biking, and climbing, this breathable, 18.5-micron merino top saw 50-plus days of testing all over the Cascades. “It’s ideal for days with big temperature swings,” says our tester. “I used it in endless combination with other layers, and was always glad to have this as the base.” The cut is long—about four inches past the waist of our 6-foot tester, and the tail extends another two inches lower—so he never experienced gaps at the waist. $60; 6 oz. (m’s L); m’s S–XXL, w’s S-XL; dale.no/us
