Weight: 2.3kg This is a large-capacity, lightweight, and waterproof 80L backpack! For long-term trekking with tent stays, a large mountaineering backpack of 50L or more is essential! When going on long mountain trips, your luggage tends to increase dramatically, so having a capacity of around 50L to 80L is reassuring (*´꒳`*) Perfect for mountain climbing and long trips, it's a unisex design suitable for both men and women. Originally produced for outdoor use, this backpack can withstand somewhat rough handling! (Please note that some parts, such as seams and shoulder parts, are thin.) Equipped with load-reducing belts on the chest, abdomen, and waist, it eliminates the need to "carry the entire weight on your shoulders," and supports the body as a whole, making it less tiring. In addition, the good balance supported by three points prevents the pack from swaying unnecessarily, which also helps protect the contents (*´꒳`*) Notes * There may be fine scratches or scuffs from the manufacturing process. Please understand. * The fabric is sewn slightly tightly to maintain its tension. There may be slight size differences. This is not eligible for exchange. * Instructions are not included. * The color may differ between the actual product and the images. Also, although it has not been used, it has been stored by an amateur, so it is considered used. Thank you for your understanding. Material: Waterproof
