Experience a minimalist design approach where less gear achieves more. By combining Houdini’s vision of circularity with Osprey’s proven performance, Allt’s technical yet sustainable materials, and versatile, year-round alpine functionality, fewer possessions and fewer decisions are all you need.

What makes it special?
The new Allt Series combines Osprey’s proven design elements with Houdini’s expertise in circularity, creating the ultimate four-season pack for alpine adventures. Constructed with advanced, fully recyclable polyester materials, these packs deliver Osprey’s renowned fit, comfort and durability combined with Houdini’s sophisticated aesthetic and circular design principles. Built to keep you moving seamlessly through any alpine pursuit with key features like A-frame ski carry, multi-functional compartments and external cinch systems that keep you ready for every challenge.

How does it work?
The pack is crafted with strong, light polyester fabrics treated with a PFAS free DWR to ensure weather protection. The 20L model is equipped with everything you need for alpine adventures all year around: Multi-use internal compartment for snow tools or reservoir, a-frame ski carry, multi-functional compartments and daisy chains to attach helmet holder. You also have a side panel stash pocket. All fabrics and webbings are made with circular materials and the plastic or metal components are designed to be easily removable to enable recycling.

When should I use it?
The answer lies in the name “Allt – Everything”. The pack is designed to be a 4-season companion for just about any alpine adventure. It works perfectly for skiing in the winter and is also light and breathable enough for summer use like hiking, camping or travelling. The versatility is a key feature: More adventure, less gear.
