Men's Arc'teryx Beta AR Jacket Color:Lodestar The updated engineered mesh upperDescription 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.
