A Circular Design Collaboration
This is Allt, a one-pack quiver for four-season alpine adventures named after the Swedish word for Everything. By combining the renowned Osprey fit, comfort and functionality with Houdini’s trailblazing approach to circular design, we really have considered everything when making this pack.
One Pack. Endless Adventures.
The Allt Backpack is born from a simple idea: Less is more. One pack that works for every season, every pursuit, every journey. By merging Osprey’s mastery of alpine design with Houdini’s vision of circularity, the Allt pack invites you to move through the mountains with freedom and ease. It means fewer possessions and fewer choices weighing you down — just one trusted companion, ready for skis, ropes, or anything else you need on a day in the alpine.

Circular by design
Sustainability is at the core of the Allt collaboration. With Houdini's technical freeride shell layer Rollercoaster as the blueprint, every detail has been considered:
Mono-material construction: All key components - fabrics, webbing, cord, and foam - are made from 100% polyester to enable straightforward recycling.
Recycled content: Main fabrics contain at least 70% recycled material, the liner is 100% recycled, and meshes are made with at least 75% recycled content.
Innovative hardware: Bio-based POM buckles derived from captured agricultural methane, recyclable polyester webbing, and removable plastic/metal parts designed for easy replacement or proper disposal.
Circular system: At end-of-life, the Allt backpack can be returned to Osprey or Houdini for responsible recycling.
