Crowded subway cars, untimely buses, achingly slow pedestrians—whatever you face on your commute, you can stay zen with the convenient storage of the Mystery Ranch Street Zen 25L Backpack. For your convenience it's got an easy top-entry Speedzip system with a two-way zipper and a buckle for added security on your commute. A padded laptop sleeve holds computers or tablets up to 15 inches, while its versatile 20L capacity is great for bikers who need a change of clothes once they get in to work. Speaking of bikers, if you're building up a sweat cycling or speed-walking to work, there's a mesh back panel and straps for cooling comfort, and an internal frame sheet for a stable carry. The front pocket has dual entries at the top and side, organizational dividers for smaller items, and is easily compressible with side buckles.
