Hollis M1 Frameless Scuba Diving Mask

The Hollis M1 is a frameless, low-volume scuba diving mask designed for clear, distortion-free underwater vision. Its ultra-clear, low-iron glass lens provides higher light transmission and reduced green tint compared with conventional glass, helping improve color and visibility in low-light underwater conditions.

The M1 features a 100% pure silicone skirt, wide vision, and a design that fits most faces. Choose the original black silicone skirt or the clear silicone skirt. The M1 Clear uses the same M1 design with a clear skirt that creates a brighter, more open visual experience and can improve peripheral awareness, particularly in low-light conditions.
