Diaper for mountaineering

Does anyone have experience with this, seems it would be cold to have to go normally, chaffing comes to mind, but staying warm seems attractive too.

By mountaineering meaning as in hiking? A diaper that is fitted right can be used for any activities. I'm very active outdoors and wear disposable diapers 24/7.

I would have no problem hiking wearing a diaper. The diaper would need to be changed when needed. If your worried about chaffing, then use a good lotion or Vaseline in groin area.

My wife and I go hiking in our local mountains often and I always my cloth diapers and rubber pants. Usually I wear pretty baggy shorts and a t-shirt. We carry my diaper bag with us along with another backpack for water and snakes. My wife has changed me several times on our hikes where we like find a spot to throw a blanket down, have our lunch and if I'm too wet, she will change me. Its private enough that someone passing by is rare, although I was seen a couple of times in my diapers.

When I go camping I used catheters.
