Choosing the wrong wetsuit thickness is how divers end up shivering through safety stops or overheating in tropical shallows. This episode breaks down the full wetsuit versus shorty debate with practical guidance based on over 8,000 logged dives in Florida waters. Whether you're planning Caribbean reef dives, cold-water wreck penetrations, or tropical snorkeling trips, you'll learn exactly which configuration matches your diving conditions, body type, and bottom time requirements.

• Full wetsuits win for any water below 78°F, extended bottom times, or cold-sensitive divers, while shorties excel in 80°F-plus tropical shallows where mobility matters more than thermal protection.

• Water conducts heat 25 times faster than air, which means your body loses core temperature long before you actually feel cold—a 3mm shorty i ...
