What does "dry suit" diving provide to the diver?

"Dry suit" diving primarily provides thermal protection by keeping the diver dry in cold water conditions. Unlike wetsuits, which are designed to let a small amount of water in that warms up against the skin, a dry suit is sealed to prevent any water from entering. This allows divers to wear insulating layers underneath, which significantly enhances thermal comfort in colder environments. The insulating properties of the suit help maintain body warmth by trapping air and insulating material, making it essential for divers operating in cold-water conditions.

Understanding this function is crucial, especially for divers who frequent colder locations where hypothermia can pose a serious risk. The suit's design is beneficial because it not only keeps the diver warm but also allows for a wider range of thermal protection options by varying the thickness of the insulating layers worn underneath, granting divers additional versatility and safety.
