Exposure Protection

[mattd]

I've read that theory, but I'm not sure I buy into it.  Wetsuits work because they try to trap the water by your skin so that you aren't losing as much heat - ie the water that your body lost heat to warm up stays put instead cold water being there.  The thicker the neoprene, the longer that water will stay warm.  Or, at least that's what I thought.

In that case, priming it with warm (not hot) water should just save you from having to lose the heat to warm it up.  The water in the suit ends up about the same whether it came from body heat or the cooler.

Of course, this all falls apart when you pee in the suit.........
