   Semi-dry suits are effectively wetsuits with watertight seams and nearly watertight seals at wrist, neck, ankles and zip. They are typically used where the water temperature is between 10 and 20 °C (50 and 68 °F). The seals limit the volume of water entering and leaving the suit, and a close fit minimises pumping action caused by limb motion.

Where the air temperature is higher than the water temperature, shallow water may be warmed by the air and the sunlight but deeper water remains cold resulting in a lowering of temperature as the diver descends.
