At Essex Scuba, we love dive gear that delivers real performance underwater, and the Hollis M1 Mask is one of those masks that consistently impresses divers of all experience levels.
If you’re looking for crystal-clear vision, rugged reliability, and superb comfort, the Hollis M1 is an absolute standout. What makes this mask so popular is the ultra-clear Saint-Gobain Diamant® lens. Compared to standard tempered glass, it allows significantly more light through, giving you a brighter, sharper, and more natural underwater view — something UK divers really appreciate in lower visibility conditions.
The frameless design keeps the mask lightweight and low volume, making clearing easy and helping it sit closer to the face for an excellent field of vision. Whether you’re exploring wrecks, diving quarries, or heading off on a tropical trip, the M1 feels streamlined and incredibly comfortable in the water.
One thing we hear time and time again from customers is how well the skirt seals. The soft silicone creates a secure fit without excessive pressure, making it comfortable even during longer dives. It’s a mask that feels dependable from the moment you put it on.
The build quality is exactly what you’d expect from Hollis — simple, tough, and designed for serious diving. No unnecessary gimmicks, just excellent optics and reliable performance where it matters most.
