Hollis Onyx

The mask glass is made from Saint-Gobain, a highly transparent, extra clear glass known for its unique appearance and optical qualities. The low iron oxide content ensures optimal clarity. The light transmission is higher than that of conventional glass. The use of extra clear glass provides a practically colorless product, allowing objects to maintain a vibrant and natural appearance. This results in a distortion-free lens that enhances visibility, even in poor lighting conditions underwater.
