And it's a good thing that they aren't porous, or they'd be pretty bad at keeping people warm! I don't surf, but I had a scuba certification when I was younger

And it's a good thing that they aren't porous, or they'd be pretty bad at keeping people warm! I don't surf, but I had a scuba certification when I was younger. My instructor told us to pee in our suits if we were getting into cold waters or found ourselves having passed through a particularly unpleasant thermocline. It saves a few minutes of discomfort while you wait for your body to heat the water trapped by your suit. It doesn't seem to add any additional cleaning steps either.
