I just dove in Belize at Christmas. Water was 80 F. I wore a full length 2 mm Jane and 2 mm jacket with long sleeves. That's a total of 4 mm on the torso, and I was cold. The people in shorties were freezing. The weather was cloudy and about 80 F also, so we didn't warm up much sitting in the boat between dives. I was really glad to have my own suit with me. The two piece is nice, 'cause if you get too warm, you can dive without the jacket, or just unzip the jacket for more water to flow through. I'm only 120 lbs, and have very little fat, and not much muscle either, so I get cold fast. My husband is the opposite - lots of muscle and fat, but he was happy to wear his 3/2 full piece. Have a great trip!
