Very good choise. I like to use cotton briefs, wool pantyhose and navy blue sweatpants to pee outdoors, Has not yet had the courage to pee in to light gray sweatpants outdoors. But I gather.
You can used wool trousers and underwear when peeing in cold weather.
The wool keeps you warm even when wet and gives an exciting feeling. I pee in heavy woolen tights in the winter when I was 6 to 9 years old. Just a pleasure. Now I pissed on my wool tights and used thick wool socks as diapers. It gives a longer warm feeling when weting and hiking in winter.
