Need a BIG bag for school.?

If you wanted to get some bag option than i would suggest Caselogic CSAM-15 Canvas 15.4-Inch Artist Series Messenger Bag for school.There is a large pocket on the back with a Velcro close, Its large enough for papers, and can fit wider things but they will bulge. Perfect for my over-sized laptop.It has great extra storage spaces. The design and fabric are awesome. And it rides nicely on my shoulder.
