if i buy a 14+ in a full suit and I need a shorty to go over it as well for diving in cold water...should i purchase a 14+ shorty to do so? Or do you recommend doing an 18 in the full suit and a 14+ in the shorty?
I dove in 38 degree water and a full 7mm with a 3mm vest underneath was very warm (and I get cold easily). I literally couldn't move with a full 7mm and 7mm shorty combined. If you really want that combo, I would go with the full in the small size and wear the shorty over it. The shorty will need to be significantly larger. Probably an 18 will work. It will be hard to move. You might even be too warm. Good luck.
