M1 Mask – Ultra-Clear Glass for Unmatched Underwater Vision
The M1 Mask is designed for divers who demand exceptional visibility and optical clarity in every dive. Featuring an Ultra Clear lens made from low-iron content, this mask eliminates the green tint found in standard lenses, delivering higher light transmittance and true-to-life colors even in low-light underwater conditions. This distortion-free lens ensures your vision stays sharp, accurate, and comfortable, whether you are exploring coral reefs, deep wrecks, or diving in challenging environments.

Built with a frameless 100% pure silicone skirt, the M1 Mask offers a secure and comfortable seal for all-day wear, while its wide vision and low-volume design allow for effortless clearing and an expansive field of view. The result is a mask that not only improves your underwater experience but also reduces eye strain during extended dives.
