$50 · Tech-Savvy Mark Ryden Backpack 50 o.b.o.

USB charging cord with inside pocket for recharger Many accessory pockets Fits 15" laptop Super comfy with lumbar support pad/pocket Loop to put headphone jack through. Pockets even on the straps Waterproof bottom (FINALLY) Combination lock (dunno where the key is or if there is a keyhole sorry. never even used it. seemed overkill) Pretty much pickpocket-proof unless they have a really big hunting knife and then... getting your laptop stolen maybe isn't your biggest problem. Seems a bit linty in the pics but I assure you it's good as new and makes you feel like you're a super spy
