TALL new diver

[Hochi]

I agree a skin is great a fleece lined one is even better if the water temp is over 80 degrees, or you are swimming so much that the exercise is keeping you warm, but if you take time to move slow and see all there is to see or if you are into getting that great photo shot I would wear something.
As far as very few people wear wear wet suits while in the Caribean this person must only go in the summer when the water is above 85 In my travels I see a lot of wet suits and even Cardean Dry Suits. So if you have one bring it so you don't have to rent. It's up to you.
