The EZ-Open mask strap has a push button release for easy donning and doffing. The mask has a double feathered edge skirt and a wide style mask strap that combine to create a perfect seal on the face. The lenses of the mask are made from an ultra-clear glass. Standard glass has a green tint. The green tint you see is the result of iron impurities left over in lower quality float” or window type glass. That green tint distorts true colors and blocks out some of the light that reaches the eye. Ultra clear is a new and exciting optical quality tempered glass with exceptional clarity and high light transmission, with no color distortion. The exceptionally high light transmittance and lack of distortion in the ultra-clear lens maximizes the light available for improved visual acuity, especially underwater in low light conditions, Better vision, truer colors are what you get with Scubapro’s Ultra-Clear lenses. Mask comes with a protective mask box.
