To enjoy backcountry skiing (BC) safely and comfortably, you'll need to carry a variety of items, primarily essential gear. A backpack to store all of this is an essential BC accessory, but what kind of backpack is best? Let's take a look at some tips for choosing a backpack and pick out some of the latest models that interest you
Points to consider when choosing a backpack
Backpacks are always worn when climbing or skiing. Because a backpack is used as if it were one with the skier under snowy mountain conditions, there are several points to consider when choosing one. Roughly speaking, these are capacity, functionality, rigidity, waterproofness, packability, thinness, lightness, and fit
capacity
The first thing to consider when choosing a backpack is its capacity. First of all, the type of backcountry skiing you plan to do will determine the equipment you'll need, and the size of the backpack you need to store it will also depend on the type of equipment you plan to use. Here are some guidelines:
| capacity | BC scenario |
| 15ℓ or less | Lift-accessed backcountry |
| 15 to 25 liters | Short BC tours with a duration of less than 3 hours, including day trips and hikes |
| 25-35 liters | Longer BC tours, such as day trips and hikes lasting more than 3 hours |
| 35-45 liters | Tours that involve overnight stays or entering the alpine area |
shovel for safety . For a day-long backcountry trip, you should bring climbing gear (skins), backup insulation, a water bottle, spare goggles and gloves, and a first aid kit. Depending on the duration of your trip, you'll also need snacks, a thermos bottle, and a headlamp.
If you plan to spend the whole day in the mountains enjoying backcountry camping, you'll need a backpack of around 30 liters. Going deeper into the mountains, you'll need crampons, a harness, ropes, and an ice axe, so you'll want more capacity. The more experience you gain with backcountry camping, the more you'll appreciate the importance of backups, and the more you'll carry. If you're new to backcountry camping, it's best to start with a backpack that can hold the bare essentials without making it too heavy.

Storage capacity
An important point is whether the necessary equipment can be stored neatly and easily without getting mixed up inside the backpack. A two-compartment structure is convenient for BC use. This is because if there is a compartment separate from the main body where you can put your climbing skins and wet gloves, which will get covered in snow, you can keep your other luggage dry
It's also a good idea to have a suitable storage space for a shovel or probe. If this area is spacious, it's also a great place to put anything that has leaked. It's also convenient to have a pocket on the top of the backpack so you can quickly change your goggles if they fog up. Some types have a roll-down expansion section from the top that expands the storage
Functionality
Backpacks have a variety of functions, but these are the main points to consider
- What kind of attachment functions are there for skis and snowboards (diagonal or A-frame)?
- Is there rear access for easy access to the contents?
- Does it have a back height adjustment function?
- Adjustment functions for the shoulder straps, waist belt, and harness?
- Are the zippers and buckles easy to use even with gloves on
? - Are there appropriate pockets for goggles, tools, small items, etc.?
- Is there easy access to avalanche gear?
- Is it equipped with an airbag
- Does it have a helmet holder?
rigidity
Considering that BC equipment can be quite heavy, it's best to choose something that is strong and rigid, reducing the strain on your body. Even if the contents of the backpack are heavy, the load is distributed, and we recommend something that is stable and less tiring to wear, and that doesn't slip easily. In addition to the materials used, pay attention to the structure of the shoulder straps, waist belt, back panel, etc
waterproof
In snowy mountains, a backpack must be highly waterproof to withstand various weather conditions and keep the inside dry even when spending long periods of time in the mountains. Backpacks with durable, highly waterproof fabric on the surface give a sense of security. It is also best to use waterproof zippers on the pockets
durability
A backpack used in harsh natural conditions also needs to be durable. It needs to be sturdy enough to withstand rough handling and not easily tear or damage when hitting trees or rocks. Some backpacks also have reinforced parts with high-strength materials that come into contact with the edges and bindings when attaching skis or snowboards
Fit
The fit when wearing the backpack is an important point. Whether hiking or skiing, you want to feel a tight fit between the backpack and your body. If the backpack swings around on your back too much, it not only makes it difficult to move and lose balance, but also wastes excess energy.
The fit depends not only on the height of the back panel being suitable for your body, but also on the quality of the back panel specifications and the adjustment functions of the shoulder straps, harness, and waist belt. The fit is also closely related to the thinness of the backpack. The thinner the backpack, the easier it will fit to your body. It's a good idea to pay attention to thinness as well.
Weight (lightness)
Naturally, if you pack the necessary equipment, it will be quite heavy. If you want to lighten your load even a little, it's a good idea to focus on the lightness of the backpack itself. The larger the capacity, the heavier it will be, and adding an aluminum frame will make it even heavier, but even if it's the same 30 liters, for example, the weight of the backpack can vary considerably depending on the material used and the features installed

AIR BAG (Avalanche Air Bag)
In addition to the beacon, probe, and shovel that are essential for backcountry skiing, you should also get an avalanche airbag if possible. While there are still fewer users of airbags in Japan compared to Europe and the US, there's no doubt that using one will increase your safety. Be sure to check out the product videos released by manufacturers
The role of avalanche airbags
Avalanche airbags are safety gear that, if caught in an avalanche, instantly inflate like a car airbag, lifting the body to the surface of the snow, making it less likely that you'll be buried. They also help reduce the impact of hitting trees or rocks, and if the balloon shape of the airbag wraps around the head, like the MAMMUT model, they can also help protect the head
How Avalanche Airbags Work
The backpack contains an airbag. To activate it, a balloon inside the backpack instantly inflates when the trigger is pulled, and the resulting buoyancy helps lift anyone caught in an avalanche as close to the surface as possible. There are two types of operation:
compressed gas type and electric type. Compressed gas type has the advantage of being simple in structure, powerful, and relatively lightweight, but the cylinder needs to be refilled after each use. Electric type can be recharged with a battery charger and can be used repeatedly.
BCA

BCA's FLOAT series of airbags are available in 12, 22, 32, and 42 liters. It features a cylinder filled with compressed air, and the air pressure drives a turbine inside the unit. The system draws in surrounding air, causing the balloon at the top of the backpack to open. It's activated by a mechanical trigger, making it easy to feel and ensuring reliable operation regardless of temperature. However, the cylinder needs to be refilled after each use.
