Open Box Hollis M-3 Frameless Mask Color:Black Featuring a metallic silver faceplateThe M3 Mask provides distortion free vision and a superior fit. The low profile design uses a rigid frame and two lenses with UltraClear glass. The low iron content produces a higher light transmittance and a reduced green tint inherent in other glasses. This makes the lenses distortion free and helps improve color and visibility in low light conditions underwater. Optical lenses from 1. 5 to 8. 0 diopters available.
