Hollis is world-renowned for its regulators, BCDs, and rebreathers, so to see so much detail on a small piece of equipment like the Hollis M1 puts them even higher on the list of manufacturers you should buy from.

Clear vision is the most important factor when it comes to ranking masks, and the M1 offers it in abundance.

Wearers will love the extremely wide, panoramic field of view and a lens made from Saint-Gobain glass, which reduces green tint and produces a higher light transmission.

This is one of the most comfortable masks on the market, delivering a silky smooth feeling from a feathered, double-edged silicone skirt, easily adjustable buckles, and a wide split strap.
