My family went to John Pennycamp in Florida, we dove 35 feet and it was February. I wore 3mm boots, gloves and a hoodie. I was warm enough. The water temp was 75. I don't like being cold at all, I wore a rashguard under my suit. I was happy in this suit, very pleasant. Pleasure Sports has been my families hub for wetsuits for years. They take care of any warranty issues on behalf of their customers and I have always experience excellent customer support.
