We loved Bottom Bumpers. They fit my huge boy and my skinny dinks. They worked well for my heavy wetter as there is room for boosting (I added a thin trifold hemp booster). They are also so slim that I could put 'sposie only' trousers over them.
I like pop ins- only thing i would say is that they are a smallish one size nappy if that makes sense, my lo outgrew these before tots bots and bgs. I also give a for using pop ins at night
