Thank you for viewing. This is the expedition backpack "alpinist130" released by the Norwegian outdoor brand "Bergans". It is a model that has been loved for a long time as Bergans' flagship backpack. This product is the 5th generation model. The current model is the 6th generation. Capacity is 130L. The material is 1300D ballistic nylon for the main body and 210D Cordura for the lower part, ensuring very high strength. The load capacity is approximately 40kg, and aluminum and fiberglass rods are used for the frame to support the weight. Specifically, the aluminum frame is in the center of the pack and the hip belt, and the fiberglass rods are placed on both sides. In addition, shock absorbers (red resin parts) are provided at the bottom of each frame (Photo 5). Side pockets are equipped on both sides, and can be removed as needed, and the capacity can be expanded by opening the zippers. Furthermore, the removed side pockets can be connected to be used as an attack pack (Photos 6-9). The hip belt has a double structure of thick cushioning and a resin frame, and has high rigidity. Also, loops for towing a sled are attached, as is typical of Nordic backpacks (Photo 10). The back length can be adjusted by changing the attachment position of the shoulder harness (Photo 11). A dedicated pack cover is included (Photo 12). It has never been used after being purchased new. It has a very large capacity, so the situations in which it can be used may be limited, but how about it for long-term outdoor activities or long trips with a backpack?
