Thanks for the suggestions. I thought about the Molicares as well. I should have clarified that he is looking for disposables, not cloth. He is really tall but also very thin, so I'm not sure if the dry 24/7s will be too big for him but I see they have sample packs.
the large Dry 24/7's sag on me after I use them to the extent that I think they will leak. Though this is solved by doubling them up but then I can barely pull my pants up over it and the diaper rides VERY high. So pretty much anyone that has a 32 inch waist or so shouldn't be buying medium/large dry 24/7's or try wearing them in public.
