Visibility is the most important aspect of any dive. The M1 mask raises the bar for optical quality and distortion free vision. This lens is an extra clear glass which is valued for its attractive appearance and optical qualities. The low iron content produces a higher light transmittance and a reduced green tint inherent in other glasses. This makes the lens distortion free and helps improve color and visibility in low light conditions underwater.
NO LIMIT
Hollis engineers superior technical diving equipment. We are intensely focused on providing diving solutions to fulfill our customer’s needs: owning the best technical diving products for their complex diving experiences. This philosophy comes from our founder and industry pioneer Bob Hollis—a man with no limits when it comes to technical diving. In the 1950s with diving still in its infancy, twenty-something-year-old Hollis pushed boundaries by building his own equipment to fuel his passion for the underwater. The ensuing decades saw Hollis innovate and disrupt—pioneering dives to the Andrea Doria—and develop reliable and dependable products that not only launched the technical diving industry but pushed the limits of tech diving into the adventure-seeking, curiosity-driven passion it’s revered as today.
Our best-in-class authority and experience leads every stage of product development, serving both the tech diver and educating the rec diver towards a brand-new category of diving. From backplates, wings, harnesses and lighting systems, to sidemounts, rebreathers and instrumentation, we concept, engineer, test and test again to ensure we remain the leading global provider of all technical diving equipment.
Divers around the world proudly bear the Hollis mark, committing their trust to the brand that challenges their limits.
