A dry suit is a type of waterproof garment designed to keep the wearer dry in cold water environments. Unlike wet suits, which allow water to enter and warm up against the skin, dry suits create a sealed barrier that prevents water from getting inside. They are commonly used in activities like scuba diving, kayaking, and cold-water swimming. Dry suits are typically made from materials like neoprene or tri-laminate, which provide insulation and flexibility. They often feature seals at the neck and wrists to prevent water entry, and many come with built-in boots or socks. Proper fit and maintenance are essential for optimal performance and safety.
