This pack is awesome!
I needed something that can accomodate:
climbing shoes (2 pairs)
extra tape, brushes
I sometimes head directly to the gym after class, so having a pack that can fit my gear as well as my school stuff is awesome. Its dedicated laptop pocket is rad, and the side pockets fit a nalgene! This thing is sleek and the compression straps keep everything from flying while you're biking around in the crazy traffic of Berkeley. Best school pack I've ever had!
