Which style do you have?
One is the the Alvar, which I use as my everyday purse and have also used it at Disney. The organizations is really nice - the bottom front zipper I use just for my phone, so it's easy to slide in and out. The upper zipper on the very front I use just for my Kipling wallet - I have a long narrow one and it slides in and out very easily. I don't put anything else in those pockets so that I know when I'm grabbing either my phone or my wallet, nothing else is falling out. There are two main compartments with zippers on the very top, I have more than enough room for everything else in there. I even carry a very large glasses case for my prescription sunglasses and I'm surprised by how well everything still fits. My favorite part about it is that it lays flat against my body and the strap width is very comfortable, and adjustable. If I don't want it crossbody, I just shorten the strap and can sling it over my shoulder.
My other bag is the Europa. It's a larger bag, and I use it sometimes as my daily bag, but most often as the bag I carry when we go on day trips (zoo, nearby big cities, etc), when I need to be able to carry more. It fits my ipad, plus a lot of other stuff, great pockets for phone, snacks, anything. I also love how it lays flat against my body when it's not stuffed to the brim. But it can hold a ton in a pinch if I need it to; I've had both my kids sweatshirts, snacks, my phone, ipad, sunblock and even small purchases we might make all in there, with room to spare. And it's super lightweight on it's own. I have also carried it at Disney when my kids were younger and we needed to lug around more "stuff."
Kipling has the best zippers - it seems like a small thing, but they're so smooth and there aren't any open pockets, so I can toss the bag around with no fear of anything coming out.
I also have one of the backpacks, plus a wallet as I mentioned. And I'm always on the hunt for what my next one will be. I like to see them in person at Macy's, but find better prices on Amazon.
