Arc'teryx Beta

Engineered for mountain versatility, the Arc'teryx Beta Pant Men pairs a PFAS-free 3L Gore-Tex ePE membrane with a recycled face and a quiet, soft Gore C-Knit™ backer for complete waterproof, windproof protection that remains highly breathable. Chira™ nylon inserts add four-way stretch and airflow exactly where you need it, while the regular fit allows uninhibited movement and room for mid-layers.

Built to perform across changing alpine conditions, the pants feature a low-profile stretch waistband with an internal drawcord for a secure, comfortable hold, and ¾-length side zippers deliver rapid ventilation and easy on/off over boots. A zippered thigh pocket keeps valuables safe, while laminated instep patches guard against crampon and ski-edge abrasion. A built-in Recco® reflector enhances backcountry searchability, adding a quiet layer of safety wherever you roam.
