The brothers behind Billykirk and red-hot retailer J. Crew recently released this rendition of the 196 Bike Messenger Bag. Made of a dusky waxed cotton, this medium-sized bag will fit a 13" laptop and is designed to sit securely on the waist thanks to an adjustable strap. It features two side pockets that accommodate water bottles, two interior pockets, a zip pocket, and a back slash pocket. The leather trim adds a touch of class and the nylon lining makes it easy to clean. It's also got a removable strap that allows you to carry it like a briefcase.
