Abstract
This diverse face mask has a frontal and two optional side self sealing lenses in a pliable mask body. Two pocket hinges are located on the sides of the mask. The Teat portion of the mask contacts the head behind the concave surface of the temple. The mask body contacting the head is concave, to act as a suction cup. A floating strap attached at the rear of the pocket hinge is provided to pull the posterior of the hinge and a posterior flap toward the body in order to provide a universal fit and water tight seal.
