This bag was specifically designed to give you more with less. Despite its compact package, the bag is jammed with features and 18 liters of storage space. It's made from a polyester/cotton water-repellant outer layer, a durable canvas base, and a 100% nylon liner. The padded laptop sleeve holds up to a 15" MacBook pro, and there's plenty of pockets both inside and outside in addition to water bottle sleeves. Your goods are easily accessible through the large drop front opening, giving you quick and easy access to your stuff. Finishes included genuine leather straps and a quick-grip top handle.
