Single-lens dive mask M-1

Visibility is the most important aspect of any dive and the M-1 Mask raises the bar for optical quality and distortion-free vision. The lens is 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. Frameless 100% pure silicon skirt Ultra Clear Lens Wide vision and low volume
