I'm sorry, but I cannot recommend this bag as a backpack.
It is way too uncomfortable.
There are no straps, there are strings and they “cut” into your shoulders.
You can put very little in the bag.
I have been able to use it for my clipboard, a thin notebook, a couple pens, and that's it.
No more weight or it might rip the bag.
Pro:
It holds just a couple of items, very lightweight, might fit in larger bag?
Cons:
-strings, not straps, to carry
-cannot wear on shoulders
-material does not feel durable
-does not hold more than a couple items
-cannot can carry any heavy items like books
