Prepration-H makes wipes. They are simply saturated with witch hazel. I use them all the time, in the wild and at home. I do not use them for medical reasons, I just hate the smell of baby wipes and think these clean better. And with witch hazel they work on other body parts too. Kind of like alcohol wipes but much more gentle on those special places.

They are flushable. In the wild, I use TP for gross decon and then do a final cleaning with the wipes. I then gather all the TP and wipes and either stick in a ziplock or drop in the fire if we have one.

As far as TP for hiking, I steal rolls from work. The rolls there have no tube and when they are nearly out the custodial staff will swap them out and leave a roll about 1" to 2" in diameter, which are the ideal size for sticking in my pack.
