Hollis M1 Onyx Mask
The Hollis M1 Onyx Mask has an excellent wide vision with a single lens, is 100% frame less and pure silicone. The lens is Saint-Gobain Diamant with a low iron content. This produces a higher transmittance, making the lens distortion free, and also helps improve visibility and colour in lower light conditions under water. Finally, with the nose pocket being soft silicone, equalising becomes even easier.
