Streamline backcountry transitions with the Firn 28L Backpack—built for ski-mo speed

What Our Gearhead® Experts Are Saying:


"I love how the Firn carries like a running vest but still packs all my ski mountaineering essentials. The ski lasso system is a game-changer—I can stow skis without stopping, which makes transitions so much faster. Plus, the crampon pocket and avy tool storage are right where I need them."


When we’re chasing dawn patrol turns or sprinting to tag a summit before work, the Osprey Firn 28L Backpack becomes our ultimate companion. Designed with insights from alpine athletes, it blends the close-to-body comfort of a vest-style harness with the technical storage we need for fast-moving mountain days. The ambidextrous ski lasso system lets us stash skis on the go, while a flexible snow-shedding backpanel keeps the load stable and light as we scramble, skin, and descend.


Every detail of the Firn is dialed for alpine efficiency. From the quick-access crampon pocket and avy tool compartment to the detachable helmet net and reinforced ski loops, this pack is built for steep ascents and fluid transitions. With its carbonate-coated fabric and bluesign®PRODUCT construction, it’s both tough and responsibly designed—ready for countless missions into pristine backcountry terrain.
