Grovia first then flip. I don't care for the PUL exposed in flip covers but the elastic is very gentle. Grovia mesh holds pad folded flats really well IMO!
Softbums got stinky for me when we pad folded. Although I like the idea of no rise snaps, super adjustable & good Velcro.
Prefer snap closure for grovia & flip. Grovia aplix is strong but I don't care for the complicated laundry tabs. Flip aplix is marginal.
