What is the role of dry suit undergarments?

The role of dry suit undergarments is to provide insulation and maintain warmth even if some water enters the suit. This is crucial for divers as dry suits are designed to keep the diver dry, but it is possible for a small amount of water to leak in, particularly during movement or at entry points. The undergarments are typically made from materials that trap heat effectively, ensuring that the diver remains warm in cold water conditions. This thermal protection is essential for safety and comfort during dives, particularly in cold environments where hypothermia can become a risk. Therefore, the insulation properties of the undergarments are a key feature that enhances the effectiveness of the dry suit.
