The Hollis M3 is a low-profile, two-lens mask with a rigid frame. The extra clear glass offers you distortion-free vision on all your dives, even in low-light conditions. This is due to its enhanced optical qualities. A higher light transmittance and a reduced green tint are achieved with low iron content.
With Hollis’ M3 you get a low volume mask that is easy to clear. However, the mask still offers you a wide field or vision, so you can see comfortably what’s going on around you.
The mask further features a soft silicone skirt that seals around your face in a very smooth way, providing a superior fit.
