Pinnacle alpine protection and all-day comfort without the weight. Lightweight durability of Pertex® and breathable waterproof AscentShell™ makes for fast-and-light performance you'll bring everywhere. See why it's trusted in the harshest environments on the planet.
Expert fitted, tested, and trusted on the West Ridge of K2.
Two powerful technologies fuse into one hard shell that feels good, protects better, and far surpasses the performance of heavier jackets. 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. Find out what makes this alpine shell roof-of-the-world ready when you try it on yourself.
