A dry suit is a type of waterproof garment designed to keep the wearer dry while engaging in activities like diving, kayaking, or sailing. Unlike wet suits, which allow water to enter and warm up against the body, dry suits create an airtight seal, preventing water from getting inside. They are typically made from materials like neoprene or trilaminate and are equipped with seals at the neck and wrists. Dry suits are often used in cold water environments, where maintaining body heat is crucial. They can be worn over thermal undergarments to provide insulation. Many divers and outdoor enthusiasts prefer dry suits for their versatility and ability to extend the diving season in colder climates, making them essential for activities in places like the Arctic or Antarctic.
