Hollis M1 Mask offers a frameless design and distortion-free vision. The lens is ultra-clear glass 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 frees the lens distortion and helps improve colour and visibility underwater in low light conditions.
Hollis M1 Mask features
- Frameless 100% pure silicon skirt
- Saint-Gobain Diamant - Crystal Clear Lens
