Built for demanding mountain operations and relentless wet-weather conditions
The Outdoor Research Allies Mountain II Bib delivers uncompromising waterproof protection, durability, and freedom of movement in a mission-ready design.
The lower shell combines AscentShell™ waterproof technology with rugged Cordura® nylon, providing over 30K waterproof protection while remaining breathable and flexible enough for high-output movement. A softshell upper improves comfort around the torso, while the highly articulated Combat Fit is designed to move naturally with the body and accommodate additional layers and equipment.
Full-length YKK® AquaGuard® side zippers make it easy to put the bib on over boots and layers while also providing quick ventilation when activity levels increase. Reinforced scuff guards protect high-wear areas from rocks, ice, crampons, and abrasive terrain, while integrated boot gaiters help keep snow and debris out.
Purpose-built storage includes high-volume thigh pockets, a dedicated transceiver pocket, and additional secure zippered storage, keeping essential equipment accessible in harsh conditions.
Whether operating in sustained rain, wet snow, or severe alpine weather, the Allies Mountain II Bib is designed for professionals who need dependable protection without sacrificing mobility.
