Hollis Mask M 1 1

The vision is the most important aspect of any dive. The M1 mask raises the level of optical quality and distortion-free vision. This lens is made of very transparent glass which is valued for its attractive appearance and optical qualities. The low iron content produces higher light transmittance and reduces the green tint inherent in other glasses. This makes the lens free of distortion and helps improve color and visibility in low light conditions underwater. A skirt made of 100% pure silicone without Saint-Gobain Diamant frame - clear vision, wide view, and low volume.
