Hollis M4

The Hollis M4 Diving Mask has been designed to give you the best of both worlds.  It fits a wide variety of faces and offers superior peripheral and vertical vision. It is low profile, stows easily and represents excellent value.  The Hollis M4 Mask raises the bar for optical quality and distortion free vision for you. This is thanks to the use of the Saint Gobain Diamante Crystal Clear Lens. This extra clear glass lens, contains a low iron content producing a higher light transmittance and reducing the green tint inherent in other glasses. This makes the Hollis M4 Mask lens distortion free and helps improve colour and visibility in low light conditions underwater.

The Hollis M4 Mask gives you a frame-less, 100% pure silicone skirt designed to sit comfortably on your face. The mask provides wide vision and low internal volume making equalising a breeze
