Built to standup to the harsh environments of Alpine Climbing the Mountain Hardwear Xenon Jacket for Women will work as hard as you do when making a push for the summit. Constructed with GORE-TEX®PacLite & GORE-TEX Performance Shell the Xenon is lighter more breathable and just as waterproof as any other jacket out there but is also very abrasion resistance and will ward of snow rocks and ice. Pull open the water-resistant zip pits when you begin to work up a sweat and when the wind begins to howl put on the Ergo Hood large enough for a helmet but with one-handed fit adjustments if you are only wearing a beanie.
