Overland is a brand I always seem to come to, the reason being that their purses are very practical, they always have good pockets and organization, and are durable. The last few years I've been using a diaper bag so I needed something that could still carry sippies, snacks, changes of toddler clothes, and my stuff without being huge nor cramped. The Donner is perfect. Here's what I really like:

-Side water bottle pockets easily hold sippies. They are upright, so no leaking.
-Back open pocket, this is perfect for sliding your keys into, I consider it a necessary feature on all bags!
-Plenty of room in main compartment for wallet, reusable shopping bag, a few small toys and snacks, and extra toddler clothes.
-Super smooth zippers
-Front pocket has organization for my smart phone, mints, sunblock stick, lip balm, swiss army knife, hand sanitizer.
-Cross body design so totally hands-free and easy to put on. No sliding off the shoulder like the usual foo-foo bags you see women struggling with.
-The peacock color is a very pretty blue-ish/green. Sporty but feminine.

This bag carries everything I need but is still light and easy to carry, I really have no complaints. Love it.
