I bought this backpack for my 15 year old son. I was worried it might not be big enough for all of his school supplies, but he said it all fits great! He really likes the look of this backpack, and loves that it glows in the dark. Even though it is a little smaller overall size than his previous backpack, he said it fits him just fine.
Only time will tell how long it will hold up to a teenagers abuse, but one week in, and all is well. :-)
