Diving mask M1 HOLLIS

Diving mask M1 HOLLIS

The visibility of HOLLIS M1 diving mask is exceptional. This mask whose skirt is made of 100% silicone, has a single glass made by Saint-Gobain, the "Crystal-Clear".

This glass is designed with a low iron content that gives this dive mask a superior light transmission and reduces the green tint inherent in other glasses.

This reduces distortion and improves colors and visibility in dark conditions.

The HOLLIS M1 mask also has a small internal volume.
