Hollis M3 Diving Mask




The Hollis M3 Mask aims for perfect visibility with a low profile, framed mask fitted with Saint Gobian Diamant crystal clear glass and a 100% pure black silicone skirt.


Stylish Matt Finish on the frame, skirt and strap but the sealing face of the skirt has a standard smooth finish for a perfect seal. The skirt incorporates reinforcing ridges down the side and underneath the buckle to prevent the skirt from creasing and collapsing when moved, which would otherwise compromise the seal.


High Grade Crystal clear glass from Saint Gobian to improve clarity and light transmittance. Standard tempered glass has a green tint that is created by iron and other impurities in the lens. Impurities scatter and reflect light as it enters through the lens, reducing the amount that is able to pass through and also affecting colours. Crystal clear glass has an especially low iron and impurity content which reduces distortion and improves low light visibility and colours.


Tear Drop Shape lenses improve the field of view to the side but also when looking down. The reverse teardrop shape to the lower frame combined with the raked angle skirt brings the bottom of the frame back in toward the face and moves the frame out of the field of view. This not only improves lower visibility without the need to tilt the head but also reduces the internal volume of the mask.


Four Way Buckle system improves strap positioning and comfort but also reduces the stress transferred to the skirt, helping to prevent the skirt from being buckled and creased through movement. The buckle assembly is able to swivel up and down for vertical strap adjustments and also in and out to allow varying fitting angles. A simple one button strap length adjustment makes final strap tightness corrections quick and easy.

I'm a frameless mask fan, but tought on given these a try. Best two window mask I've experienced, period. Visibility is superb and confort. Will use frameless only as a back up now, after I've discovered the Hollis M3. Also very good looking! :)

Superb fit and comfort, low volume and excellent clarity through the lens. The storage box is very robust. Great service from simply scuba.

Superb mask, did not realise the difference between a good quality snorkel mask and diving mask until my original mask gave up the ghost at 90 feet!! A superb fitting and high quality mask.

Great mask made better by the removable Gopro mount

Excellent quality mask and it feels great on face. However, it is very limiting on peripheral vision, the black skirt can make it feel a little like tunnel vision.

Bought this mask for my first season working as an instructor, very sturdy mask with perfect vision, no difficulties with it at all. Has survived over 100 dives this year and has taken a beating in the shop as well. No scratches or tears at all. V
