In order to enjoy the backcountry (hereinafter referred to as BC) safely and comfortably, you will need to bring various items, mainly the necessary equipment. A backpack to store them is a must-have for BC, but what would be good? Let's pick up points on how to choose a backpack and pick up the latest models that you are interested in.
Considerations when choosing a backpack
In BC, I always carry a backpack, whether I'm climbing or skiing. Because it is a backpack that can be used as if it were one with the slipper under the conditions of snowy mountains, there are multiple points to check when choosing it. Roughly speaking, it's about capacity, functionality, rigidity, waterproofness, storability, thinness, lightness, and fit.
capacity
The first thing to consider when choosing a backpack is capacity. First of all, depending on what kind of BC scene you are going to skate in, the necessary equipment will differ, so the size will change to store them. Below is a guideline.
| capacity | Assumed scene of BC |
| 15ℓ or less | Backcountry with lift access |
| 15〜25ℓ | A short BC tour within 3 hours including day trips and hikes |
| 25〜35ℓ | Longer BC tours such as day trips and hikes that take more than 3 hours and all day long |
| 35〜45ℓ | Tours with overnight stays and entering the alpine area, etc. |
Even for lift access backcountry skiing, the minimum necessary avalanche gear such as
shovels On a one-day BC tour, you should have climbing gear (skins), back-up insulation wear, a water bottle, spare goggles and gloves, a first aid kit, etc. Depending on the time of action, what should you do with action food, thermal bottles, and headlamps? , and so on. If you want to enjoy BC in the mountains all day long, you'll still need a backpack around 30 liters.
If you go deeper into the mountains, you will need to carry crampons, harnesses, ropes, ice axes, etc., and you will want more capacity. The more experience you have with BC, the more you realize the importance of backups, so the more you carry. If you're new to BC, it's a good idea to start with a backpack that holds the bare minimum of equipment so that it doesn't get too heavy.
BC one-day tour basic equipment
storability
An important point is whether the necessary equipment can be neatly stored in the backpack without being jumbled up. The two-room structure is convenient for BC use. That's because having a separate compartment for snow-covered climbing skins or wet gloves keeps your other gear dry.
Also, it is good to have suitable storage space for shovels and probes. If this part is wide, it will be the best place to put the leaked stuff. Also, it is convenient to have a pocket on the top of the backpack so that you can quickly replace the goggles if they fog up. Some types have a roll-down expansion part from the top to expand storage.
Functionality
There are various functions of backpacks, but the point of focus will be like this.
・What is the attachment function for skis and snowboards (diagonal, A-frame)
Whether it is easy to access the internal items from the back
・Whether the back is equipped with a height adjustment function
・Shoulder belt, waist belt, and harness adjustment function
・Whether the zippers and buckles are easy to use even with gloves on
・Whether there are appropriate pockets for goggles, tools, small items, etc. ・Whether it
is easy to access avalanche gear
・Equipped with an airbag
・Whether there is a helmet holder
rigidity
Considering that the BC equipment is quite heavy, it is better to have a rigid one that reduces the burden on the body. Even if the contents of the rucksack become heavy, the load is distributed and it has a sense of stability, so it is difficult to get tired and slippery. In addition to the materials used, we also paid attention to the structural parts such as the shoulder straps, waist belt, and back.
Waterproof
A backpack with a high level of waterproofness is essential so that the inside does not get wet even if you spend a long time in the snowy mountains. A backpack that uses a highly waterproof and robust fabric for the surface fabric gives a sense of security. The zipper attached to the pocket should also be a waterproof zipper.
durability
We also want durability for backpacks used in harsh natural conditions. I want it to be strong enough not to be easily torn or damaged even if it hits a tree or rock, and not to be shaken by a little rough handling. In addition, there are also those that are reinforced with high-strength materials where edges and bindings interfere when skis and snowboards are attached.
fit
The fit when carrying is an important point.
You can get a feeling that the backpack and the body are in close contact with each other when hiking or sliding. If the backpack sways too much on your back, you will lose your balance and not only will it be difficult to move, but it will also consume extra energy. The fit is supported not only by the height of the back matching your body, but also by the completeness of the specifications of the back part, the shoulder straps, harness, and the adjustability of the waist belt. Also, the fit is closely related to the thinness of the backpack. The thinner it is, the easier it is to adhere to the body. You should also pay attention to the thinness.
weight (lightness)
If you put in the necessary equipment, it will naturally become quite heavy. If you want to lighten your luggage even a little, you should stick to the lightness of the backpack itself. The larger the capacity, the heavier it will be, and if you add an aluminum frame, the weight will increase even more. occur.

AIR BAG (avalanche airbag)
In addition to the beacon probe shovel essential for backcountry, I want to get an avalanche airbag if possible. Compared to Europe and the United States, there are still fewer users in Japan, but there is no doubt that safety can be ensured by using it. Let's take a look at the video of the product released by the manufacturer.
Role of avalanche airbags
The avalanche airbag is a safety gear that instantly inflates like an airbag in a car before it buries itself, lifting the body to the surface of the avalanche to prevent burial. It also reduces the impact of collisions with trees and rocks, and if the shape of the balloon wraps around the head like the MAMMUT model, it also helps protect the head. .
How Avalanche Airbags Work
An airbag is built into the backpack.
When the trigger is pulled, the balloon inside the backpack instantly inflates, and the buoyancy of the balloon lifts the person caught in the avalanche to the surface. Operation can be divided into those using compressed gas and those using electric power.
The compressed gas type has the advantage of being simple, powerful, and relatively lightweight, but the cylinder must be refilled after each use. The electric type can be used repeatedly by charging with a battery charger.

FLOAT 32

yen for a set of 32ℓ body and cylinder

It is a system that takes in the surrounding air and opens the balloon at the top of the backpack. The mechanical trigger makes it easy to get a feel for the operation, allowing reliable operation that is not affected by temperature. Cylinders, on the other hand, require refilling after each use.
