Which of the following items is NOT a hypothermia clothing type used by the Coast Guard?

• A. Surv Coveralls
• B. Dry Suit
• C. Wet Suit
• D. Floatation Vest

Answer: (D)

The key idea is clothing that protects you from losing body heat in cold water. Dry suits keep you completely dry and insulated, often with warm undergarments. Wet suits rely on a trapped layer of water next to the skin that your body heat warms for insulation. Survival coveralls provide substantial insulation and protection during cold-water exposure. A flotation vest, while important for buoyancy and visibility, does not offer insulation or thermal protection to prevent hypothermia. Therefore, it isn’t considered hypothermia clothing.
