Outdoor Research Allies Mountain II Jacket | AscentShell Protection for Extreme Missions

Built for the storm. Ready for the fight. Just Released.

The Outdoor Research Allies Mountain II Jacket is engineered for those who don’t get to choose the weather. Designed for military, law enforcement, and alpine professionals, it combines AscentShell™ Dry waterproofing with Cordura® nylon ripstop durability to deliver elite protection in the harshest terrain. From relentless downpours to freezing alpine winds, this shell keeps you dry, mobile, and mission-ready.

Constructed from a 75x160D Cordura® ripstop shell with a 30D tricot backer, the Allies Mountain II offers abrasion resistance that stands up to thick brush, rough rock, and hard use. Fully seam-taped and built with articulated patterning, it maintains unrestricted mobility for dynamic movement under armor or gear. The helmet-compatible hood features a wire brim and full adjustability for precise coverage, while the forearm stash pocket, internal mesh dump pocket, and internal chest pocket provide organized storage for mission essentials.
