The Boundary's unique no-center post lens design provides unobstructed forward vision and peripheral vision. Unlike conventional center post mask designs, the eye no longer has to constantly refocus to a changing water-air interface while the swimmer is breathing. Stainless steel screws bold the UV and anti-fog lens securely to an ultra-light frame creating a watertight bond with unparalleled clarity. Translucent silicone gasket increases light absorption. Split silicone head strap with easy side locking adjustment. Features durable polycarbonate frame, soft hypo-allergenic silicone seal and silicone head strap with easy side locking adjustment.

Patented side wrap, screw-on one piece lens for uninterrupted forward and peripheral vision.

Optical grade polycarbonate lenses are anti-fog, anti-scratching and UV protected.
