This Owl E multifunctional diaper backpack is as great to look at as it is to work with.  The high-grade nylon fabric makes it lightweight and sturdy, which is important when carried as a backpack wherever you go.

The wide-open design has a large interior with a zippered pocket and three elastic bottle-friendly pockets inside.  Its front section has three elastic pockets and a net pocket ideal for milk bottles and more.

What's also great about these backpacks is their versatility.  Once it's outlived its usefulness as a diaper bag, use it as a gym bag, school bag, or overnight bag.
