I use the depend protection with tabs plastic backed diapers for when I'm at home and they do a pretty good job of absorbing my urine.
But I don't trust the depends protection with tabs too much when away from home. Not really because of absorbency but because of the tapes coming loose.
The tapes aren't all that strong and don't really hold up good to walking and being active. Other than the tape problem the Depends are pretty good absorbent diapers.
