The Hollis M1’s main selling point is absolutely is field of view – it’s a great mask just from first glance! Even from looking briefly at the design, you can tell that this is a mask that’s got an extremely wide field of vision.
However, there’s more to it than just size. This mask fits the bill thanks to its Saint Gobain diamant crystal clear manufacture – and what’s more, the lens is made from extremely low iron – a perfect attribute for performance in low light environments That means you can expect a distortion free experience while diving, and that what you see is largely 100% pure ocean life!
This mask is also made of high quality material throughout, meaning you not only benefit from clear glass and high light transmittance, but also anti fogging, comfortable buckling, and a great seal against water ingress. You only have to check out customer reviews to see more of what I mean.
