This bag was ok. I sold it because it was too bulky and kept tipping over. I'm not an overpacker either so this one didn't work out for me. But it was very easy to access stuff on top. The bottle layer, not so much because of the taper that makes the bottom smaller than the top.
bottom layer
top layer (adding anything in the top zipper pocket makes it hard to get to the stuff in the mesh pockets below it)
Mom pocket (worthless IMO, putting anything in here makes it tip over and soo bulky). Hardly any organization.
Bottle pockets (again, adding anything in here creats a ton of bulk)
For some this is a great bag. But most agree that it's very bulky.
