When we've skied every run on the mountain a few times over, and our eyes drift towards the outskirts of the resort, we're glad to be wearing the Mountain Hardwear Boundary Ridge GORE-TEX Jacket, so we can plow through deep stashes of untouched powder in comfort. The breathable GORE-TEX membrane seals out moisture while allowing hot air to escape, and two zippered vents cool us down fast when we work up a sweat on grueling boot packs.
