Khaki Large Capacity Backpack School Backpack Commuting Backpack Mountaineering Backpack I think it can be used in all situations, such as commuting to work or school, and mountain climbing. It can easily hold 3 2-liter plastic bottles, and also a lot of magazines and books. (Please check the 4th photo) Height 42cm x Width 33cm x Depth 23cm This is just a rough measurement. There are no noticeable stains. Regarding the condition, it is based on my personal subjective opinion and has been stored and used by a layman, so please refrain from purchasing if you are sensitive to this. Price reduced!
