What is the significance of the seals on a dry suit?

The seals on a dry suit play a critical role in ensuring the suit's effectiveness in keeping the diver dry and safe during underwater excursions. These seals, typically made of neoprene or latex, create a barrier that helps prevent water from entering the suit. When secured tightly around the wrists and neck, the seals maintain a snug fit, which is essential for limiting water ingress. This is particularly important as any water that enters the suit can significantly reduce thermal insulation, increase the diver's weight, and potentially lead to discomfort or hypothermia in cold water situations. Therefore, the primary function of the seals is to keep water out, allowing the diver to stay dry and maintain body temperature, which is essential for comfort and safety during dives.
