Arc'teryx Men's Beta AR Jacket

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.

What's been updated: Updated with GORE-TEX PRO ePE fabrics, free from intentionally added PFAS. New patterning minimizes fabric waste, saving 800 metres of material—the equivalent of 400 jackets—in the production process. Enhanced fabric lamination and updated cordlocks improve durability.

Arc'teryx Layering Guide

Layers are the instruments of keeping you dry, warm and using your energy efficiently. Put into the right systems, a good sequence of layers provides you with weather protection, moves moisture away from your skin, conserves or dissipates heat, and does this in the least amount of time.
