For the past six years Seadive/Oceanways has developed and field tested, anti-reflective (ARC) mask coatings of tempered glass. Seadive/Oceanways ARC coatings now allow almost 100% transmission of light. Standard tempered glass has a minimum of 4%-plus rate of reflection which can seriously distort underwater vision. Only Seadive/Oceanways has licensed application and laboratory fabrication. Only Seadive/Oceanways has six-plus years of dealer/customer satisfaction. XS Scuba's Seadive Rayblock Monarch HD Mask provides the Best overall for any and all diving/snorkeling conditions. The lens reduces harmful UV/glare, surface grit in eyes and provide overall greater clarity. When you come up for a dive the lenses provide quick vision-return from surface making this the instructor's choice in mask design. The Rayblocker Monarch HD Mask low volume design prolongs the need for equalizing and allows for easy clearing. The buckles of the mask are positioned directly on the skirt minimizing weight and reducing drag. The XS Scuba Rayblocker Monarch HD Mask has a single tempered glass lens, a high quality silicone skirt and head strap.

## Customer Reviews

### ⭐⭐⭐⭐⭐ All around awesome mask
*by A***R on December 15, 2021*

Love this mask!! Fits perfectly and doesn't leak.

### ⭐⭐⭐⭐⭐ The best !!!!!
*by L***O on May 5, 2014*

Just returned from diving with this mask in Cozumel. This is the BEST mask I have ever owned. Super comfortable.

### ⭐ Just because it didn't work for me doesn't mean it won't work for you.
*by S***. on July 11, 2021*

For me this mask was a no-go. It didn't fit well it leaked like a sieve it was definitely not a good fit for my face. That being said it doesn't mean it won't fit your face. I have more of a round face. Basically you have to try them on for yourself to see if they work for you.
