To maximize protection from hypothermia, the dry suit should be worn with what undergarment?

• A. Regular underwear
• B. Thermal underwear
• C. Wool coat
• D. No undergarment

Answer: (B)

Under a dry suit, you want an insulating layer that also manages moisture. Thermal underwear provides a close-fitting, insulating base that traps air to reduce heat loss and wicks sweat away from the skin, helping you stay warmer and drier. Regular underwear offers little insulation and doesn’t handle moisture well. A wool coat isn’t designed as undergarment under a dry suit and can bulk or restrict movement. Wearing no undergarment leaves you without that insulating layer, increasing heat loss. So the proper undergarment is thermal underwear.
