What must the dry suit be worn with to provide maximum protection from hypothermia?

The dry suit is specifically designed to provide thermal protection in cold water environments, and for it to function effectively, it needs to be complemented with a thermal layer. This layer creates insulation by trapping air and retaining body heat, which is crucial in preventing hypothermia during exposure to cold water. When combined with a dry suit, the thermal layer maintains the body’s core temperature, significantly reducing the risk of hypothermia.

While options like a personal flotation device, waterproof jacket, and insulated gloves contribute to safety and protection in various ways, they do not enhance the thermal insulation provided by the dry suit. A personal flotation device improves buoyancy but does not directly prevent heat loss. A waterproof jacket may offer wind protection but lacks the necessary insulation. Insulated gloves will help keep hands warm but cannot substitute for the overall thermal protection that a good thermal layer provides when worn under a dry suit.
