For the approach, the climb, and the descent, our Ice Pack is that perfect companion that&';s never in the way, yet always right there when needed. Refined to the essence of what&';s truly necessary for success, this bomber, 100% waterproof DyneemaA(R) Composite Fabric pack features a no-frills main compartment that&';s perfect for our Pods and Stuff Sacks. External fitments securely hold crampons and ice axes, and options for gear loops or pockets on the hip belt complete the theme of well thought out accessibility to tools. Whether the day is spent on cliffs or mountains, concentrate on the climb without the distraction of cumbersome equipment. The 2400 (40L) volume size works well when basecamp for the chosen endeavor is a vehicle, and the climb is an out and back over the course of a day.
