This backpack is beautiful and large. Lots of compartments for stuff and it will hold a LOT of books. The padded laptop section will hold a 17" laptop easily and the zipper around the middle for ease at TSA is a nice bonus. However, we are returning this backpack since the strap adjustments do not stay tight. I put the bag on, tightened the shoulder straps and they immediately began coming loose. When I began to take the bag off to check the straps, they slid all the way to the end of the strap nearly coming out of the buckle. Not good for a brand new backpack. Going to see if it is a defect with the bag we received, or if this is a flaw with all the Urban 17 bags and will update later.
