Unused. - High-quality BLACK material - Many zippers and sufficient storage, very functional - Perfect for walking and light hiking Although unused, based on years of experience, I believe this backpack is designed with much better usability than backpacks for mountaineering. Mountaineering backpacks are constructed with only the essential storage compartments, lacking "nice-to-haves," while this backpack gives the impression of being designed with everyday life in mind. (I own about 20 backpacks, large and small, for mountain use and running.)
