The 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. Frameless 100% pure silicon skirt Ultra-Clear lenses Wide vision and low volume 4 way buckle design for superior comfort and storage if needed Action camera mount sold separately which allows hands free photography and video. (Hollis not responsible for loss of action camera)
