Hollis M1 Dive Mask
Visibility is paramount in any dive and the Hollis M1 Mask elevates optical quality to new heights. Its ultra-clear glass lens offers a pleasing aesthetic while delivering exceptional optics.
The low iron content enhances light transmittance, eliminating the green tint common in other glasses. This results in distortion-free vision and improved colour and visibility underwater, even in low light.
New for 2026 the M1 in Clear combines the mask’s iconic design with ultra-clear low-iron glass lenses. It also features a new clear silicone skirt that enhances brightness improves peripheral awareness and creates a more illuminated visual experience in low light making the mask feel almost invisible. The M1’s wide fit range makes the clear version a perfect addition for any diver wanting the M1 but with a brighter and more open view.
