Ice Pack 55



The Ice Pack 55 is the pack to grab for multi-day winter excursions, where volume flexibility for extra food and clothing is a critical ingredient to your success. When the extra volume is not in use, the top can roll down enough to make the overall size of the pack similar to the 40-liter Ice Pack, but that additional space can come in pretty handy when you need it.

For the approach, the climb, and the descent, the Ice Pack is that perfect companion that’s never in the way, yet always right there when needed. Whether the day is spent on cliffs or mountains, concentrate on the climb without the distraction of cumbersome equipment.


Formerly known as the 3400 Ice Pack. Packaging may have either name but the product is identical.
