From frigid winter hikes to bluebird days in the backcountry, the Beta AR Jacket rises to the challenge. Your go-to hardshell for every mountain mission, its hybrid construction holds up to snow, sleet, and strong summit winds. Ultra durable GORE-TEX PRO ePE on the yoke and arms resists abrasion, while a lighter version on the body reduces weight and bulk. The result? A fully featured jacket that delivers what you need, where you need it.
