HOLLIS M-1 FRAMELESS MASK

Visibility is the most important aspect of any dive. The M1 Mask raises the bar for optical quality and distortion free vision. The extra crystal-clear Saint-Gobain Diamant tempered glass single lens is 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 glass. This makes the lens distortion free and helps improve color and visibility in low light conditions underwater.

The M1 frameless design makes it easy to stow in a BCD pocket, so it can also be used as a back-up mask if required. Mask provides a wide field of vision with a low internal volume making it extremely easy to clear. The 100% pure silicone double feathered edge skirt and wide split style mask strap combine for a perfect seal and comfort on the face. Mask has low-profile quick adjust buckles. The M1 Mask is available in all black, comes with a protective mask box for storage.
