The ZipBaby is a convertible bag that switches to a beltbag by cinching the strap to your waist size and threading it through your belt loops or a thirds way by removing the strap and clipping the bag to your belt loops.  Measuring 8" wide x 6 1/2" tall with two inside pockets and an open space, it really is when you're rolling with just the essentials.  Lots of ecopeeps carry these inside a bigger tote. It’s also a convertible bag that switches to a beltbag by cinching the strap to your waist size and threading it through your belt loops.  

This one is butterscotch coloured vegan leather with an accent of coordinating plain dark rust wool.
