Re: snaps covers for padfolding?
I have Flips, Thirsties duo size 2, Bestbottoms, and Blueberry covers, all with snaps. The Blueberry is the roomiest with a high rise. I actually find it's too roomy for our 16 lber, waiting to see if it will work better in a few months. The Bestbottom is the smallest and has the lowest rise. The duo is good but I like my Flips the best bc the snap tabs are stretchy and the covers just seem trimmer overall. The duo covers with snaps have tabs that always seem to "show" (lumpy) under clothes.
If you don't need flaps, then maybe try a Blueberry. To me, the Thirsties duos dont seem to have much more rise than a Flip.
