Sleek, stylish, and well designed, the Osprey Arcane Large 18L Backpack is the perfect commuter pack. It features a durable waxed polycotton construction that's hard-wearing yet soft to the touch, and the internal compartment holds sleeves for everything from work folders and class notes to your 15 inch laptop. The front zippered pocket is a great place for smaller items you need quick access to, and includes a key clip so you'll never misplace your house or car key. The shoulder straps themselves are equipped with pockets, perfect for tucking a bus ticket or lip balm, and the left one includes a safety clip if you'd like to secure the pack to a table or chair leg while you stop for lunch.
