The backpack is probably not too big, but it can be still some stash. Since I did not have him long, I can not say the shelf life, but he makes a strong impression. Thanks to several zip pockets can also accommodate the things orderly. The only criticism is that zipper can be opened from the main compartment quickly and easily and therefore things are not as housed safe enough. I will therefore not secure the two zippers with a small lock. Otherwise, a handy city backpack looks good.
