Pack your shovel and probe first. You should be able to reach them without unloading your food and spare layers. Then check space for the rest of the equipment you need, how the pack fits when loaded, and how you’ll carry skis or a board when walking.
A pack, even an airbag pack, is the last line, not the first. The decisions that keep backcountry travelers alive are reading the forecast, carrying and practicing with a transceiver, probe, and shovel, getting trained, and choosing terrain conservatively. The pack organizes that system and, in the case of an airbag, adds a margin. Choose between airbag and non-airbag packs according to your touring needs.
Pack your essentials first
Pack your shovel, probe, layers, food, and water before judging the size. The rescue tools need their own accessible compartment, and everything else must fit without blocking it.

Black Diamond Dawn Patrol 32
Best Overall
The Dawn Patrol 32 combines a 32-liter capacity with a front avalanche-tool pocket, diagonal ski carry, vertical board carry, and a helmet holder. Back-panel access gives you another way into the main compartment. At 1.17 kg and around $220, it’s worth comparing as a day-touring pack. Load it with your own equipment before deciding whether the capacity and harness suit you.
Strengths
- 32 L capacity for comparing day-tour loads
- Fast-access dedicated avalanche-tool pocket
- Ski and board carry plus helmet holder, fair weight and price
Tradeoffs
- No airbag option in this model
- Diagonal-only ski carry, no A-frame
- Mid-weight rather than ultralight
- Volume
- 32 L
- Weight
- 1.17 kg
- Carry
- Diagonal ski + vertical board
- Avy tool
- Dedicated pocket
- Price
- ~$220
Best as a single do-everything touring pack. Skip it if you need an airbag or the lightest possible setup.
Osprey Soelden 32
Best Value
The Soelden 32 delivers a full-featured touring pack at the lowest price among the do-everything options: 32 liters and 1.13 kg for around $195. It has a dedicated J-zip avalanche-tool pocket, all three ski and board carry options (A-frame, diagonal, and vertical board), a helmet carry, and Osprey’s usual build quality and warranty behind it. The women’s-specific version is the Sopris, in 20 and 30 liter sizes. There is no airbag option and the organization is a touch simpler than the premium packs, but for a skier who wants a complete, well-made touring pack without overspending, it is the value pick, and the women’s fit is a genuine plus.
Strengths
- Full feature set at the lowest do-everything price
- All three ski and board carry modes
- Women’s-specific Sopris version available
Tradeoffs
- No airbag option
- Organization simpler than premium packs
- Slightly less refined back access than the Dawn Patrol
- Volume
- 32 L
- Weight
- 1.13 kg
- Carry
- A-frame, diagonal, board
- Avy tool
- J-zip pocket
- Price
- ~$195
Best for a complete touring pack on a budget, and for a women’s fit. Skip it if you want top-tier organization or an airbag.
BCA Float E2-25
Best Airbag Pack
The Float E2-25 uses an Alpride E2 electronic airbag system in a 25-liter pack. It weighs around 2.66 kg and costs about $1,300. The system avoids a compressed-gas cartridge, but it still needs the prescribed charging, maintenance, and deployment practice. Check the exact operating instructions and travel requirements before relying on it. The small capacity also deserves a trial pack with all your essential equipment.
An airbag reduces the chance of a deep burial, but it does not eliminate avalanche risk. It cannot protect against trauma from trees, rocks, or cliffs, it offers little help in a terrain trap or a deep secondary burial, and it only works if you deploy it in the moment you are caught. It is a margin on top of a transceiver, probe, shovel, training, and good terrain choice, not a substitute for any of them.
Strengths
- Electronic system with prescribed recharge procedure
- No compressed-gas cartridge
- Includes an electronic airbag system
Tradeoffs
- Heavy and expensive, as all airbag packs are
- Battery needs charge management in the cold
- Only 25 L, tight for long days
- Volume
- 25 L
- Weight
- 2.66 kg
- Airbag
- Electronic (Alpride E2)
- Carry
- Removable ski + board straps
- Price
- ~$1,300
Best for the tourer committed to an airbag who wants to practice and fly with it. Skip it if the budget or weight is prohibitive, or treat the canister Float 22 (around $550) as the cheaper entry.
Black Diamond Cirque 25
Best Lightweight
For fast-and-light touring, where every gram you carry uphill counts, the Cirque 25 is the lightest pack here that still does the job. At around 0.86 kg, a clean 25 liter body for about $220, it strips the touring pack to essentials, with a dedicated avalanche-tool pocket and a removable diagonal ski carry you can leave at home to save more weight, aimed at skiers who move quickly and do not need to haul a full day’s worth of extras. The trade is capacity and padding: 25 liters and a minimal harness are right for efficient half-day and skin-track laps, not for hauling overnight gear.
Strengths
- Lightest pack here while keeping an avy pocket
- Clean, efficient design for fast touring
- Removable ski carry to shed more weight
Tradeoffs
- 25 L is tight for long or cold days
- Minimal harness padding under heavy loads
- No airbag option
- Volume
- 25 L
- Weight
- 0.86 kg
- Carry
- Removable diagonal ski
- Avy tool
- Dedicated pocket
- Price
- ~$220
Best for fast-and-light skiers counting grams. Skip it if you carry a lot or want a plush harness.
Patagonia Descensionist 37
Best Multi-Day
When the trip runs long (a hut tour, an overnight, a big objective day), the Descensionist 37 has the volume the smaller packs lack. At 37 liters and 1.5 kg, around $279, it swallows extra layers, food, and overnight or group gear while keeping a divided dedicated avalanche-tool pocket and all three ski and board carry options. It is still a clean, ski-focused design rather than a bloated expedition pack, so it tours well when full. For day tours it is more pack than you need, but for the bigger missions it is the right size here. It is available from Patagonia.com as of June 2026, though some retailers list it as closeout, so confirm current availability before buying.
Strengths
- 37 L handles hut trips and overnights
- Divided avalanche-tool pocket and full ski carry
- Tours well for its size
Tradeoffs
- Oversized for short day tours
- No airbag option
- Heavier than the day packs when loaded
- Volume
- 37 L
- Weight
- 1.5 kg
- Carry
- A-frame, diagonal, vertical
- Avy tool
- Divided pocket
- Price
- ~$279
Best for hut trips, overnights, and big days. Skip it for short laps where a 25 to 32 L pack is plenty.
Mammut Pro 35 Removable Airbag 3.0 Ready
Best for Splitboarding
Splitboarders have a specific need, carrying two ski-shaped halves and skins on the up and a full board on the down, and the Pro 35 is built for it with a dedicated splitboard carry mount that most touring packs lack. The Pro 35 Removable Airbag 3.0 Ready is a 35-liter splitboard-capable pack designed to accept Mammut’s Removable Airbag System 3.0, sold without the system included: the pack alone is about $339, the RAS 3.0 system adds about $479, and a compatible cartridge is sold separately. That keeps it flexible, since the same pack works as an airbag pack or a standard one, but the real cost depends on how you configure it. Weight climbs with the system too, from about 1.62 kg for the pack alone to 2.32 kg with the RAS unit and 2.63 kg once the cartridge is fitted. The cartridge and its servicing requirements are part of the ownership cost. Verify the exact system against current transport rules before air travel.
Strengths
- Dedicated splitboard carry mount
- Removable airbag: run it with or without
- Solid 35 L volume for full board days
Tradeoffs
- Canister airbag needs refilling and is harder to fly with
- Pricing varies a lot by configuration
- Heavier than a non-airbag pack
- Volume
- 35 L
- Weight
- 1.62 kg pack / 2.32 kg with RAS
- Airbag
- Removable canister (RAS 3.0, sold separately)
- Carry
- Splitboard mount
- Price
- ~$339 pack / +$479 system
Best for splitboarders who want board-specific carry and airbag flexibility. Skip it if you ski rather than ride, or want an electronic airbag.
How to choose a backcountry pack
Volume
Lay out the equipment for your actual tour before choosing a capacity. Winter layers, food, water, repair supplies, and emergency equipment can take very different amounts of room. A smaller pack is useful only if everything fits without burying the rescue tools or strapping loose essentials outside. For an overnight trip, include the sleeping equipment you must carry rather than assuming a particular liter figure is enough.
Try packing the bag completely, then open the tool compartment while wearing gloves. Put the loaded pack on, adjust the harness, and turn your head with your helmet on. Finally, test the intended ski or board carry with your equipment. These checks reveal problems an empty pack in a store cannot.
Airbag or not
An airbag adds weight, cost, maintenance, and another system to practice using. It does not replace avalanche training, terrain decisions, or a transceiver, probe, and shovel. Compare the complete system rather than the empty pack: include any separately sold airbag unit, cartridge, or power source. For travel, verify the exact system against current transport rules before booking; airline approval alone is not a universal permission to carry a cartridge.
Ski and board carry
Decide how you carry. A-frame carry (one ski per side) is stable for booting steep, technical sections; diagonal carry (both skis across the back) is fast to rig for short carries; vertical or board carry holds a snowboard or splitboard flat. If you switch between booting and skiing often, a pack with more than one option is worth it; splitboarders should look specifically for board or splitboard carry.
Hydration and organization
Winter breaks hydration bladders, because the hose freezes. Many tourers carry an insulated bottle instead, stored upside down so ice forms away from the lid, or run an insulated-hose bladder and blow the water back after each sip. Beyond that, look at how the pack organizes: a separate avalanche-tool pocket is non-negotiable, and a goggle pocket, a way to reach the main compartment without dropping the pack in the snow, and ski-boot-friendly hipbelt buckles all make a difference on a cold day with gloves on.
Frequently asked questions
What size backcountry ski pack do I need?
Choose by packing your complete equipment for the intended trip. Rescue tools must remain accessible with layers, water, food, and emergency supplies loaded. A larger number on the label does not guarantee a better layout or fit. Test the loaded harness and any ski or board carry before deciding.
Do I need an avalanche airbag pack?
An airbag can help but is not required, and it is not a substitute for the basics. Statistically an airbag improves the odds of staying near the surface in a slide, which reduces burial risk, but it does not eliminate it: it cannot prevent trauma against trees or rocks, it does not help in a terrain trap or a deep secondary burial, and it must be deployed in the moment. An airbag is an addition to a transceiver, probe, shovel, training, and conservative terrain choice, never a replacement for them.
What is the difference between a canister and an electronic airbag?
Compressed-gas systems use a cartridge; electronic systems use a powered inflation mechanism. Compare the complete weight and cost, maintenance, and the procedure after deployment. Follow the exact system’s instructions, and verify carrier rules before air travel.
How does a backcountry pack carry skis or a snowboard?
Three common ways. A-frame carry straps a ski to each side of the pack, which is stable for booting up steep terrain. Diagonal carry runs both skis across the back corner to corner, which is quick to set up and good for short carries. Vertical or board carry holds a snowboard or splitboard flat against the back. Many packs offer more than one option; pick based on whether you carry skis or a board and how often you switch between riding and booting.
Can I use a hydration bladder in the backcountry in winter?
You can, but the hose freezes easily, which is why many tourers skip the bladder in deep cold and carry an insulated bottle instead, often upside down so any ice forms at the bottom rather than the lid. If you do run a bladder, look for an insulated hose and bite valve, blow the water back into the bladder after each drink so the hose is empty, and route the hose inside your jacket. Keep water accessible and check that your chosen setup works in the conditions you expect.
Match the pack to your tour
Start by comparing the Dawn Patrol 32 and Soelden 32 with your full day-tour load. Their similar capacities make access, harness fit, and carrying options useful points of difference.
If you need more room or an airbag-compatible design, compare the complete load and cost of the other options above. Leave enough room to access equipment without unpacking on the snow. The avalanche guide explains why equipment selection belongs alongside training, forecasts, and conservative terrain choices.
