Our most advanced and carefully-crafted high-altitude climbing suit yet. We worked with the world's most accomplished alpinists to redesign this suit from the ground up, refining features from oxygen mask-compatibility to a unique internal suspender system. This design was made with the highest level of focus on functionality, simplicity, and durability and has been put to the ultimate test in the Khumbu Valley. Bringing it back to our proving grounds, we've ensured that mountaineers can have complete confidence in their kit and their chances of success on summit day.
