I haven't used it much and have kept it at home. It has multiple pockets and storage compartments, and can be separated into two layers with a divider (see photo 11). Please purchase only if you understand that this is a used item. ★ Instant purchase OK I think you can use it for mountain climbing, short trips, or as an emergency evacuation bag in case of a disaster. Thank you. #CLIMBING #LargeCapacityBackpack Size...30-45L
