Peeing in your waders is probably the stupidest thing I have ever heard. The point of being in waders is to stay dry! Who would wan't to come out soaked in their own pee? :x
See, this is exactly why I don't wear waders, lol. I mean come, guys, even big bear is warm enough for board shorts right now. No need to slow yourself down with an extra 4MM of neoprene until the water cools. If you get cold, just take a swig from the old flask and you'll be sweating in no time, he he he.
I don't wear them to stay warm. I Wear them to keep my vehicle seats dry when I'm done tubing. I also wear them so I don't prune up after hours of fishing in the water. I don't get bluegills trying to pluck all the hairs out of my leg either :lol: and it's also nice to have some slight protection against line slices, hooks and catfish spines or if the fish on your stringer hit your leg as they have done already to me while in my waders. a stringer of 10 sharp *** giant bluegills or sharp stripers wrapped around your leg could do some damage!
And then when winter comes.. I'll still be warm in the water. In summer, I pull my waders off and havn't even broken a sweat. Neoprene isn't as hot as everyone said it would be 8)
IMO, waders are worth the trouble of carrying them.
