OK, so the physics make sense (As long as its a steamer at least 4mm thick
), but basically you are saying that if you go into the water unconscious without a lifejacket with a half fitted wetsuit you will drown. Agreed
But if you go into the water unconscious without a lifejacket NOT wearing a half fitted wetsuit you will drown as well.
Therefore no extra risk from wearing a half fitted wetsuit.
As we all know, dry suits are a different kettle of fish.
