Well, it's pretty...
I think the product is exactly as described. I think my needs require something else. The "L" in the description gave me the impression that it was going to be a larger backpack, than what I received.
When this pack (for my daughter) is filled with her books, it's jam packed, with no room for too many extras. With all of the books and such, it gets very heavy and the straps aren't very comfortable.
So far (after 3 weeks of school) the pack has held up the abuse of an active high schooler. I'll be cursious to see if it can make it through the year.
