Prism 40 Pack

The alpinist’s answer to fast and light efficiency.

The Prism 40 Pack is an alpine specialist, stripped down to the absolute essentials for moving quickly over technical terrain. Designed with direct input from professional alpinists, it combines the bombproof durability of woven Dyneema® with a streamlined feature set that refuses to snag on chimneys or haul loops. Whether you are tackling a single-day winter ascent or a multi-day alpine traverse, this pack carries the load on the approach and compresses into a low-profile climbing partner for the summit push.
