Hey, I started out learning scuba. Didn't end up finishing....but had already bought a full body suit....I was cold in the heated pool all the time. Since then I've taken the suit and used it snorkeling in the Caribbean in February....I LOVED having it!! I was never cold...and it provided extra bouyancy. I'm going back to the Caribbean in July and I just wondered if I would need it for snorkeling there at that time of year. I don't want to haul it around if I don't need it....but I HATE to be cold.... What can anyone else who is cold all the time tell me about snorkeling in the Caribbean in July? Thanks!
