The lightweight durability of Pertex Diamond Fuse technology keeps you agile through rugged environments, and the breathable waterproof comfort of AscentShell technology lets you move and speed up when precipitation comes down. A high-mobility, low-bulk fit takes up less space in your pack and layers more efficiently with harnesses and backpacks. Built in collaboration with Outdoor Research alpine ambassadors Emilie Drinkwater and Graham Zimmerman, this hard shell has been tested and trusted in some of the harshest environments on earth, including the world’s second highest mountain K2.
