The Hollis M1 Mask sets a benchmark for optical clarity and distortion-free underwater vision. Designed for divers who demand superior visibility, the M1 features an ultra-clear, low-iron glass lens that significantly increases light transmission while reducing the green tint commonly found in standard tempered glass. The result is sharper definition, truer colours and improved visibility, particularly in low-light or deeper diving conditions.
Its low-profile, low-volume design makes equalisation and clearing effortless, while the high-grade silicone skirt delivers a secure, comfortable seal across a wide range of face shapes. Built with Hollis’ signature rugged quality, the M1 is engineered for both recreational and technical diving where clarity and reliability are critical.
