I´m 6ft and 132lbs, wore DryNites a few times, mostly the girls ones. From a technical point, they suck. Don´t hold much, and leak in 90% of the normal sized wettings.
Besides that, they are enjoyable. Actually comfortable, Really like the designs, too. Messing also is fun in them, but they are pretty expensive.
The only suitable pullups I know are Attends Pull-Ons or Tena Pants so far. There´s also the Always Discreet pants out there, haven´t had a chance to test them yet, though, would like some info on them.
