If you’re going to immerse yourself in some of the most challenging, rugged environments on Earth, you’re going to need gear born from experience. The ultralight Prism, Ice Pack, Porter, and Summit Pack are built off the testing that the world's top alpinists perform for us. For ice climbers, mountaineers, alpinists, and backcountry skiers and snowboarders, the Prism brings speed, weight, security, and comfort into clear focus. This top-loading 40L pack is designed to excel in any scenario, and when paired with the external Prism Crampon Bag and Prism Ice Screw Case, allows adventurers to reach the pinnacle of efficient travel. 

The Porter is a rope and rack hauling pack with extensive daisy chain attachment points and an optional detachable pocket. Select any of four available volumes and bring as much or as little gear as you want. Whether it’s day trips, quick rock routes, ultralight overnights, or long approaches and self-supported ventures in the backcountry, there’s a Porter for every pursuit. If higher altitudes and tool-worthy exposures are in the works, the Ice Pack adds reinforced crampon and ice axe attachments to the Porter’s ultra-minimalist offerings. Tailor any of the three available volumes to your time out or the scale of your endeavor. Throw a Summit Pack in for fast-paced peak bagging, with only a minor weight penalty. Add our water-resistant Pods and Stuff Sacks into the mix to build weatherproofing redundancy and organization to your system.
