Since backpack is not your preferred style... I'll chime in. I LOVE LOVE LOVE my Vera Bradley diaper bag. Yup... it was a little more pricey. BUT, I have twin girls (and a 3.5 year old) and it fits all I need. Not to mention I cloth diaper... and those puppies take up some room let me tell you!
It comes in either a black or brown exterior. The outside is quilted microfiber the inside is a cute green and brown pattern that is WIPEABLE! The ENTIRE inside is waterproof. As well as the outside zippered pocket where the included changing pad is stored. There are several mesh pockets lining the inside in two different sizes. I have a place for everything.
On the outside, there is the zippered pocket and then two other outer pockets.
This bag is cute, stylish, holds everything and I LOVE it! I love it so much once I no longer need to carry a diaper bag I totally plan on using this for an overnight bag for myself!
I bought this bag when my girls were only a couple of months old. They are now 8 months. This bag has been stuffed under the stroller, hauled ALL over the place, thrown in the back of the car ... seriously been put through it's paces. And still looks FABULOUS! I highly recommend this bag.
