Patagonia's Paxat 32L Backpack helps you get through crowded campuses and airport security like a champ. The main compartment, secondary compartment, and laptop sleeve open wide for easy packing and inspecting. Patagonia built this pack out of partially recycled fabric with a DWR treatment for weather-resistance. The padded laptop sleeve protects computers as large as 17 inches, and the secondary compartment has an internal organizer.
