Why would I want to wear a drysuit in the tropics?
Warmth is a relative thing. If the water is not body temperature, or near it, you will get cold. When making multiple dives in a day over multiple days, anyone can develop a heat deficit, even in the warm waters of the Caribbean or the South Pacific. As a diver with a heat deficit, you will feel more fatigue and use more air as your body unknowingly struggles to keep warm. You can add more neoprene but once you get thicker than a 3mm wetsuit, the 30/30 becomes a lighter and more comfortable option.
