Visibility is the most important aspect of any dive and the Hollis M-1 Mask raises the bar for optical quality and distortion-free vision.

The lens is ultra-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
• Ultra Clear Lens
• Wide vision and low volume
