Dry Suit
Definition
A dry suit is an exposure suit that keeps the diver dry by sealing out water and providing thermal insulation with undergarments.
More on Dry Suit
Dry suits are essential for diving in cold water, where wetsuits provide insufficient insulation. Unlike wetsuits that trap a thin layer of water against the skin, dry suits keep the diver completely dry by using wrist, neck, and ankle seals and a waterproof zipper. Undergarments worn beneath the suit provide insulation. Dry suits require specific training to handle buoyancy, air migration, and inverted ascents. Materials include crushed neoprene, trilaminate, and vulcanized rubber.
Frequently Asked Questions
Use a dry suit in water temperatures below 15°C (59°F) or for long dives where thermal protection is critical.
They seal with tight latex or neoprene cuffs and a waterproof zipper, keeping all water out. Air is added through an inflator valve to prevent suit squeeze.
Yes. Buoyancy control is different, and improper use can lead to uncontrolled ascents or air trapping in the legs.
Common types include crushed neoprene (insulated), trilaminate (lightweight), and vulcanized rubber (used in contaminated water diving).
Rinse after use, dry fully, protect seals with talc or silicone, and store flat or hanging. Annual servicing is recommended.
