Osprey Firn Backpack is the perfect companion for steep, fast climbs and ski touring. It features an ergonomic, trail jacket-style fit and an intuitive, reversible Ski Lasso system that allows you to attach skis to the pack without having to remove it from your back. Made from 100% recycled nylon with a carbonate coating and a PFAS-free water-repellent treatment, it meets the strict bluesign® PRODUCT sustainability standards.

Main product advantages:

• Innovative Ski Lasso carrying system: The double-sided system allows you to quickly and securely attach your skis to your backpack while walking without removing your backpack (it can be stored or removed when not in use).
• Direct access to crampons and skins: A special lower side pocket allows one-handed access to crampons or skins directly while wearing.
• Quick-access avalanche equipment compartment: A dedicated front pocket for a shovel and avalanche probe allows for immediate action in an emergency.
• Snow-repelling back: Atilon and corrugated EVA foam, covered with elastic fabric, prevent snow from sticking and accumulating on the back.
• Removable frame to reduce weight: The HDPE back plate with support provides stability under heavy loads, and can be removed to reduce weight if desired.
