Rain or shine, the Columbia's Evolution Valley II Jacket always adapts. This lightweight shell features a sporty cut with plenty of stretch for wearing on the trail, but sacrifices nothing in the way of wet weather protection. It's built with a breathable, waterproof membrane and fully sealed seams, so you can move through heavy storms without getting soaked. Mesh lining helps draw sweat away from your hard-working body, but you can also unzip the underarm vents to dump heat faster. Columbia equipped it with adjustable cuffs, hem, and hood, giving you extra defenses against the prying wind or sideways rain, and added zippered hand pockets to give you a safe place for trail snacks.
