Hollis Mask M-1

Brand: Hollis

Distortion Free Viewing 

The Hollis M-1 mask is one of our most popular masks. You get a huge view, a super soft seal, and nothing is cooler than the Batman-like squared off nose. This mask is my go-to whenever my students have an issue with their mask. Works like a dream!

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 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.
