I have 3 side-snap that I got from VeryBaby. Mine actually aren't fitteds, I had them made into AIOs (it's one of the available options). I can't say how they compare to the VBVeryBasicAIOs, because I don't have any of those. But they fit nicely, with lots of room to grow. I have mediums for ds and he's on the tightest snaps. He's about 18 lbs. I *think* they're trim, but I don't value trimness like some others here do, so I may not be the best judge on that. They're quite absorbant with the lay in doubler and snap-in soaker. They're very nice for running errands and such during the day, when ds may not get changed as often as he would if we were at home. I would say they're perfect for "extended daytime use." Granted that's extended for cloth (2, maybe 3 hours???), I wouldn't leave my child in it for 4 or 5 hours. But, my ds has turned into a super-peer! I hope my rambling has helped in someway. I'm still a little incoherent from the holidays.
