Osprey Packs

Sopris 40L Backpack - Women's

What Our Gearhead® Experts Are Saying:

"I used the Osprey Sopris 40L Backpack on a two-day hut tour with a full overnight kit, avalanche safety gear, and enough food and layers for variable mountain weather, and it carried everything without fighting me on the skin track or the descent. The gender-specific harness and hipbelt shaping made a real difference over long mileage days, and the front panel J-zip kept my probe and shovel exactly where I needed them without unpacking a single thing."

Big backcountry objectives demand a pack that can keep up across the full arc of the day, from the pre-dawn skin track through a technical descent and into an overnight hut stay. The Osprey Sopris 40L Backpack is built for exactly that kind of ambition, the largest technical ski pack in the Sopris line and the one you reach for when the plan involves more than just a day trip.

The front panel J-zip gives you direct, glove-friendly access to your avalanche safety compartment, with dedicated shovel and probe organization that keeps emergency gear ready without hunting through your main storage. Dual access points at the top lid and back panel give you flexible options for getting into the main compartment depending on the situation, and a removable top lid with two zippered pockets handles the small items that need to stay close on the way up. A-frame and diagonal ski carry, horizontal snowboard carry, a dual-position stow-away helmet net, and an ice tool sleeve cover every gear configuration the day might require. The Lightwire frame threaded into an HDPE framesheet and stay keeps the load transfer efficient on long ascents, while gender-specific EVA foam harness and hipbelt shaping deliver a fit that holds steady on technical descents when stability matters most. A thermoformed snow-shedding backpanel reduces ice and snow buildup, and PFAS-free DWR treatments on Bluesign-approved fabrics round out a pack built to go further without compromise.
