Pacific Outdoor Equipment Cassette Backpack
Here's what other sites are saying:
Cram your books, a laptop, and a spare layer in the burly Pacific Outdoor Equipment Cassette Backpack and hit the town on your bike. Tough thermal welded nylon and nigh-indestructible buckles keep this pack going through seasons of two-wheel commuting. Cinch down external load-securing strap to keep the contents of your pack from shifting around, and should you hit the pavement around dusk, a reflective stripe down the back of this pack keeps you visible in traffic.
