Details

The Beta AR Pant delivers waterproof, windproof, breathable protection for comfort across these changes. The GORE-TEX PRO with Most Rugged Technology – a next-gen material we developed in collaboration with Gore – delivers maximum durability. Articulated patterning adds freedom, WaterTight™ side zips 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.
