Abstract: A dive vest and snorkel system is provided. The dive vest is constructed of air and water impervious material having an inflation chamber capable of receiving and storing air and further having an exhaust port which automatically exhausts the air stored in the inflation chamber when the wearer of the dive vest places the headmost end of the dive vest lower than the exhaust port prior to diving below the water's surface.The snokel has a tube with a mouthpiece at one end and has means for constricting the opening at the other end of the tube. These means may be either placing the snorkeler's hand in sealing contact with the end of the tube or placing a cap in sealing contact with the end of the tube by pulling a pull ring connected to pull cords which are in turn attached to the cap.
