Visibility is the single most important aspect of any dive, and the Hollis M1 Mask raises the bar for optical quality, color accuracy, and distortion-free vision underwater. Designed for technical, recreational, and freediving applications, the M1 sets the industry standard for clarity and comfort.
Engineered with premium Saint-Gobain Diamant extra-clear glass, the M1 features an ultra-low iron content that eliminates the greenish tint found in conventional scuba masks. This reduced iron formulation maximizes light transmittance, allowing true, natural colors to shine through while drastically improving contrast and visibility in low-light, deep-water, or overhead environments.
