Hollis M1 Mask
Hollis M1 Mask raises the bar for optical quality and distortion free vision.Visibility is the most important aspect of any dive. This 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 colour and visibility in low light conditions underwater.
The low profile design of the mask allows the diver to use minimal air for mask clearing.
The mask also comes with collapsable buckle which is more durable against damage.
