TIBAG 30L/35L Water Resistant Lightweight Packable Foldable Hiking Daypack Backpack

This was given to someone as a gift. But I did open it and it can hold alot of stuff.

This is a very durable backpack with a lot of room. It never ripped when my son was carrying heavy binders and books for school.

Able to withstand my son!2019 update: still going strong!

bag does not retain it's shape and is so big--which I thought would be a benefit--that is hangs very low on one's back like a heavy satchel. Terrible for back and posture.
