I remember that I got the same results to my early days of hunting, years later when I was in school in the military in the Florida Keys. And later in San Diego where the ocean water would get down into the 40s during the winter months. When I would go diving, the water between my wet suit and my skin would become a comfortable insulator and keep me warm in the cold water. Some people think that a wet suit keeps you dry, but it doesn't. The water gets between the wet suit and your skin and becomes an insulator that keeps you comfortable. Maybe that is where I got the idea back when I was a kid. I really don't remember.
Not all of them,Jim. Wetsuits are exactly that, but the drysuit was invented as far back as 1837 for keeping you warm AND dry. There is no need to be wet while staying warm anymore while diving, if you're willing to pay the price for a good drysuit.
