One-Pack Quiver for Alpine Days
RRP: £300 (20L) / £350 (30L) BUY NOW
Volumes: 20L (everyday / light tours), 30L (bigger backcountry days)
The Osprey x Houdini ALLT is pitched as the “one backpack for everything” – and, unusually, that’s not just marketing fluff. This limited-edition collab pulls Osprey’s pack know-how together with Houdini’s circular-design brain to create a four-season alpine pack that can carry skis, ice tools and avy kit in winter, then switch to hiking, climbing or travel when the snow’s gone.
Built from performance recycled polyester with PFAS-free waterproofing and hardware designed to be fully recycled at end of life, it’s as much a sustainability statement as it is a ski pack. The ALLT name comes from the Swedish for “everything” – the idea is you own fewer packs, but use this one harder, all year round.
On the Mountain
For skiing and ski touring, the ALLT feels very much like a proper alpine tool rather than a lifestyle daypack.
- Ski carry: Reinforced A-frame ski carry plus deployable cinch straps let you lash skis securely without them flapping around on bootpacks.
- Avalanche kit / hydration: A multi-use internal compartment is sized for shovel and probe but can double as a reservoir sleeve in summer – neat if you don’t want a pack that screams “skier” year-round.
- Rope & tools: Rope compression strap, removable front accessory straps and ice tool attachment keep technical hardware under control when you step into steeper terrain.
The adjustable AirScape™ back panel has been tweaked to shed snow, so it doesn’t turn into a frozen sponge on storm days, and the CCubed foam stays surprisingly breathable when you’re skinning or bootpacking.
The only real trade-off is weight. At around 1.46kg for the 20L, it’s heavier than a minimalist touring pack of the same size – but you get more structure, comfort and durability in return.
Design, Fit & Everyday Use
You can tell this is Osprey-built as soon as you sling it on:
- Carry system: Injection-moulded framesheet plus padded hipbelt and load lifters give enough support for full avy kit, water and extra layers without feeling like a slab on your back.
- Back panel: Close-to-body fit keeps the load centred for technical skiing or scrambling, with foam that pulls moisture away so it doesn’t get swampy on warmer tours.
- Access & organisation: Roll-top closure lets you cinch the volume down or over-stuff it, side stash pocket takes skins, snacks or gloves, and internal layout is simple enough not to fight you with gloves on.
Off the mountain, the clean silhouette and minimal branding make it work as a travel or commuter pack, especially in the 20L size. The 30L is better suited to hut trips, guiding days or mixed climbing/ski missions where you’re carrying more hardware and insulation.
Sustainability Story
Where the ALLT really stands out is how deeply the circular design thinking runs:
- 100% polyester key components (fabric, webbing, cord, foam) to simplify recycling with minimal disassembly.
- Main fabrics use high recycled content, with recycled liners and mesh.
- Bio-based POM buckles and recyclable polyester webbing are designed so the pack can be returned to Osprey and fully recycled at end of life.
- PFAS-free DWR and bluesign®-approved materials back up the eco claims.
If you’re trying to cut down on kit and buy longer-lasting, repairable gear, that’s a big tick.
Pros
- Proper four-season alpine pack – ski touring, freeride, climbing and hiking in one
- A-frame ski carry, rope strap, ice tool attachment and avy kit compartment all built in
- Supportive AirScape back panel with snow-shedding, breathable CCubed foam
- Robust, weather-resistant build with Dimension-Polyant RX36 and recycled poly fabrics
- Genuine circular design: single-stream polyester components, PFAS-free DWR, recyclable hardware
- Two volumes (20L / 30L) cover both short day tours and bigger missions
Considerations
- Heavier than a pure ski-touring race/lightweight pack in the same litre range
- Roll-top plus rope strap is brilliant for security but slower to get in and out of than a full-zip panel
- Limited-edition collab – stock and colour options are likely to be tight
- Premium price tag versus simpler day packs

InTheSnow Verdict
The Osprey x Houdini ALLT isn’t trying to be the lightest pack on the skintrack – it’s trying to be the only pack you need all year. If you want one bag that can handle resort laps, sidecountry hikes, full ski-tour days and then roll straight into summer alpine and travel duty, this hits that brief impressively well.
Yes, you pay a weight and price premium, but you get serious carrying comfort, proper ski-mountain features and one of the most thought-through sustainability stories of any pack out there right now. For skiers who like the idea of a “one-pack quiver”, the ALLT makes a very strong case.
