Constructed of a burly, waterproof 600D, urethane-coated polyester, these bags are built to last in your fast-forward world. Quick-Clip™ closures allow for easy access to an external zip pocket, and an internal organizer keeps your stuff at your fingertips. An internal divider and corner pockets add commuter-smart organization, and the innovative Modular Accessory Pocket (M.A.P.) system attaches Zip Pockets or Mobile Electronic Cases. The shoulder strap provides one-handed adjustability and both it and the back panel are padded, waterproof and ventilated for comfort. The finishing touches are good clean looks, carry handle, bike-friendly hideaway waist belt and a light clip-loop to keep you visible. There's no built in laptop sleeve on the Urban Shoulder Bag so if you'll be using this for a laptop bag you'll need to add a separate sleeve.
