No wrinkles and no stink mean that we wore this shirt straight from the trail to the airplane. A Polygiene treatment on the polyester knit banishes odor, and the fabric resists wrinkles even after being packed for days. The weave is airy and soft against skin, and the fabric’s UPF 50+ rating combats UV. It also breathes well: “On a three-day backpack in New Hampshire’s White Mountains, I wore this shirt for sun protection but never felt too swampy, even in 80°F weather,” one tester says. After a rain shower in the Whites, it dried in less than two hours, even with the humidity.
