Vapor barrier works by letting the skin get wet and keeping the insulating layers dry. Nothing, no matter how woolly or poly, is as effective at insulating when it’s damp. If you’re in neoprene rubber rubber booties, that sweat isn’t evaporating, anyway. Definitely effective and one forgets about the slimy feeling.
