Sizing is off
I ordered pull-ups and the regular ones. The straps on the regular ones have absolutely no stretch so they were too small. The pull-up style ones were nice at the waist, however they didn't have enough coverage around the bum so one side or the other would always end up as a wedgie in his bum. I would have loved the pull-up style if only they had more coverage on the bum. The other ones are a bit bulky and need work on stretch around the tummy area and the straps. I couldn't use the non pull-up ones. Unfortunately I won't be ordering again.
