The Osprey x Houdini Allt 30L is a four-season alpine backpack that merges Osprey's ergonomic design with Houdini's circular material principles. The shell combines recycled 75D polyester on the front with 300D x 600D recycled polyester reinforced with polyethylene film on the sides and base, all finished with a PFAS-free DWR treatment for weather resistance. A-frame ski mounts, ice tool attachments, a rope compression strap, and an internal compartment sized for avalanche equipment make it ready for demanding mountain objectives, while its breathable CCubed foam back panel and padded hip belt keep it comfortable across summer hikes and multi-day trips alike.
