Familiarity: I've put it through the wringer
So I started with some similar looking bag from Nixon that was just not what I needed. I got this one on an exchange and it's amazing. The top pocket is roomy enough that I keep a 15mm wrench, lights, chain oil, and various other items in it. the bottom pockets hold my two calculators, a huge pencil case, various school related objects and occasionally some headphones. On the inside i can carry at least two engineering textbooks, an engineering pad, 2 note book and then throw a jacket on top or my lunch box. On top of that I can easily get my 17' laptop in the back. The across the chest strap is helpful as this is a pretty heavy load to bike back and forth to school everyday. Overall it's an awesome bag. The only con is that I'd like a loop to hook my rear bike light on. right now I just hook it in an open rear pocket. Also it would be awesome if the zips had two zippers so that you could lock them if you're doing some sketchy urban travel.
