The ZipBaby is a sweet, small bag for just the essentials.  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 what you need and no more.  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 has smooth black vegan leather with printed vegan leather accent.  Look for more bags with this print! build a matching set.
