Thermal protective aid is a bag or suit made of waterproof material with low thermal conductance. all sailors, commercial fishermen, and crew members onboard cargo vessels maintain their immersion suits, which offer better visibility and prevent them from drowning. It also provides hypothermia protection and saves from extremities as it is made of waterproof material.
