Abstract

Abstract A streamline face mask for swimmers which can be used with either a snorkel or underwater air equipment is secured to the head of the swimmer to provide a smooth surface over the face and across the head of the swimmer and thereby reduce drag. The shape of the mask is determined by a pair of connected side members which cooperate to form a forwardly projecting prow portion and a centrally positioned relatively sharp edge which extends longitudinally from the prow.
