The urban backpack can be worn as a sling bagg, or unzip the straps and reattach them to make a comfortable backpack. There are outside zippered pockets on both the front and the back, and the contrasting color inside makes it easy to find whatever you are looking for. Unzip the sides and this bagg opens completely to reveal two zippered pockets, a cell phone pocket, lipstick and pen holders and even pockets for ID and credit cards. The sides are gusseted to keep items secure. Made of lightweight, water resistant crinkle nylon.
