Hollis M1 Frameless Mask

The Hollis M1 Frameless Mask is built around a low-volume single-lens design with high-clarity Saint-Gobain Diamant tempered glass. The low-iron lens improves light transmission and reduces the green tint common in standard glass, helping deliver a bright, distortion-free view underwater.
