A dry suit or drysuit provides thermal insulation to the wearer while immersed in water, and is worn by divers, boaters, water sports enthusiasts, and others who work or play in or near cold water. The drysuit protects the whole human body, except the head, hands, and possibly the feet. Drysuits are used typically in these cases:
where the water temperature is below 15°C (60°F).
for extended immersion in water above 15°C (60°F), where discomfort would be experienced by a wetsuit user.
with an integral helmet, boots, and gloves for personal protection when working in and around hazardous liquids.
