Woolen undergarments will work regardless what its made for...
Yeah but you are a polar bear. There is NO WAY I would get in the water with what you wear, as I would be frozen in five minutes. What you wear is what I wear UNDER my undergarments.
Much of what you require for undergarments, and base layer depends on water temps, and how you dive. Some are quiet divers that move very slowly (OR quickly if using a scooter, but that makes you colder), with really long 80+ minute bottom times, and some divers are hyper underwater constantly moving and tend to have shorter bottom times -30 minute bottom times. Of course some people are more predisposed to the cold than others.
