The Granville 20 Backpack hits the point where a utilitarian messenger bag and refined urban backpack come together. Highly water resistant AC² (Advanced Composite Construction) technology shields contents from rain and snow. The large main compartment is accessed by a custom Arc\'teryx one-handed release buckle. A padded sleeve secures a 15 inch laptop and organizes documents. A stretch mesh zippered pocket stores chargers and cables. Pockets under the flap hold wallet or smartphone, and a clip-in point secures a bike light.
