Why We Like It

Having a lightweight base layer is an essential piece for any smart traveler. It keeps you comfortable without having to take it on and off while you're moving through variable temperature ranges like airport terminals. REI's lightweight half-zip top is a bargain, as other brands typically sell similar products for twice as much, albeit with more features like a chest pocket and thumb loop holes.
