Hollis, M-3 Black mask

This low profile design uses a rigid frame and two lenses with an extra clear glass which is valued for its attractive appearance and optical qualities. 

The low iron content produces a higher light transmittance and a reduced green tint inherent in other glasses. This makes the lens distortion free and helps improve color and visibility in low light conditions underwater. 



Features:

• - Frameless 100% pure silicon skirt
• - Saint-Gobain Diamant - Crystal Clear Lenses
• - Wide vision and low volume
• - 4 way buckle design for superior comfort and storage if needed
