When diving, the cold is your worst enemy. This is still the case when back on dry land or on the boat. Wind is a real problem for divers. It cools the water and the air contained inside the neoprene diving suit, making divers feel very cold. The coated fleece material of this poncho protects you from the wind and provides extra warmth. Divers can stay warm, even when they are still wearing their damp diving suit.
