Wind, then sleet, snow, then sleet again – mountain weather is never constant. The Beta AR Pant delivers waterproof, windproof, breathable storm protection and performs across a variety of mountain activities. The GORE-TEX PRO with Most Rugged Technology – a next-gen material we developed in collaboration with Gore – delivers maximum durability. Articulated patterning extends comfort, WaterTight™ side zippers provide drop-seat functionality, and a hidden RECCO® reflector improves searchability in emergency situations.

The Beta AR Pant is produced at multiple facilities to balance manufacturing capacity.
