Hello Lori, here is the size chart for the sizing of the mask: SIZES: Small-Medium Faces (50-110 lbs), Medium-Large Faces (110-220 lbs), XLarge Faces (220 lbs+).
Bio-Metal Mask Apollo's Bio-Metal offers the largest field of vision. Plastics and other materials used for the average mask require a thicker frame to remain stable. Using aluminum allows the Bio-Metal frame to be produced with a very low profile while still supporting a twin lens design. Twin lens design is preferable to single because it brings each lens closer to the eye for a wider field of vision and reduced inner volume. Aluminum also allows for a very minimal center pillar. The slim-line center pillar is narrow enough to have almost zero effect on field of vision.
Divers often feel a slight distortion of view. Cause: lack of alignment between the lens and actual eye center. Correction: Our lenses are ground like a sphere to provide optimum efficiency at the center of the lens. The lens center is designed to more naturally match that of your eye. The Bio-Metal mask provides superb clarity and 180° field of vision.
Comfort is just as important as vision. The high quality surgical silicone flange is soft and designed to collapse accordion style, eliminating stress points on the delicate facial area. Built-in drainage channels allow a diver to clear without lifting off the face. Just look up and exhale lightly through the nose.
The low profile frame and soft flange make this an excellent fitting mask for almost any shape face.
