Lol I've never thought of using them, tho I'll pack some tp into just about every thing possible. I'll put a roll in my pack with about a 1/2 of paper on it, a good wad in my main heavy jacket and coveralls if I have them.
Heck the mauser m18 I'll be using has that compartment in the butt stock that will get a small amount lol. Gives new meaning to butt stock lol.
