Hollis M1 Diving Mask




The Hollis M1 Mask provides every thing that you could want in a diving mask, ultra low profile design, super soft superior quality silicone skirt, frameless construction for improved field of vision and reduced weight and optical grade glass for improved clarity and light transmittance.


Saint-Gobian Diamant Crystal Clear Glass that has a significantly lower iron content than standard glass. This reduction in iron removes the green tint that is often apparent in cheaper glass and allows more light to filter through the glass without being reflected back out by the impurities. Colour distortion is also reduced, giving true colour representation.

  • Saint-Gobain Diamant - Crystal Clear Lens
  • Wide vision and low volume
Dive Type Scuba
Lens Coating Saint-Gobian Diamant Crystal Clear Glass
Lens Type Single
Mask Frame Frameless

after using the Poseidon tech mask and feeling like i was suffering with tunnel vision, this mask lets so much light in due to it shallow frame. would highly recommend to others

The mask fits well and is far easier to clear (taking my Divemaster certification right now). The mask is comfortable and is compact enough to be a backup mask in my drysuit or BCD pocket.

I was actually looking at a different mask, but that was out of stock, and I'm glad it was the Hollis M1 is a really nice mask! and I'm glad I got this instead! I would strongly recommend this mask!

Initially I had problems with fogging despite using toothpaste on the glass, probably due to residue left on the glass from the manufacturing process. However after a few sea dives, no issues. The silicon skirt is very comfortable on the face.

perfect mask. it's my second one

With previous masks due to a very pronounced masculine brow I found that the mask frame pressed into my head and caused leaks and discomfort, the M1's frame-less design is very comfortable and I would recommend for anybody with this problem.

Great mask - tried it for the first time yesterday and was instantly impressed. Very comfortable and great view - the low profile enables excellent peripheral vision. I would strongly recommend this mask to anyone looking for an upgrade.

Great mask, no problems recommending this to others!!

Excellent mask! Price is almost half of what I've found in Belgium so far. Small hint, like for most masks: clean it before using it (e.g. with toothpaste)...

10 April 2012

The lens needs to be cleaned with something stronger than the usual toothpaste. I cleaned it twice using dishwashing liquid and hot (not boiling) water, and it seems to do the trick. Comfort is amazing and it is indeed crystal clear...

What a great mask, crystal clear, fogged up the first one or two times I used it, but I just left it coated in toothpaste overnight after the first few uses and it was fine. A small price to pay for such a great product and I haven't had to do it sin

When the Mask arrived I tryied it on and found a nice comfortable fit. To prepare the mask I put toothpaste on the glass and left it over night giving it a good clean next day. 2 days later of I went diving and having completed 5 dive had no problem
