What is the primary purpose of layering undergarments in a dry suit?

The primary purpose of layering undergarments in a dry suit is to enhance thermal insulation. When diving in colder waters, it is crucial to maintain body heat, and the right undergarment layering can significantly improve thermal protection without compromising mobility or comfort. These layers trap warmth generated by the body while providing additional insulation from the cold water around the suit.

Materials used in undergarments are designed to wick moisture away from the skin, ensuring divers remain dry and warm. Effective thermal insulation is essential for safety and comfort during dives in low-temperature environments, as it helps prevent hypothermia and ensures that divers can focus on the dive itself rather than being distracted by the cold.
