HOLLIS MASK M-1

Visibility is the most important aspect of any dive. The M1 mask raises the bar for optical quality and distortion-free vision. This lens is an extra clear glass that 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.
