Hollis M1 Frameless Scuba Diving Freediving/Spearfishing Dive Mask

This is a great mask for both technical and recreational scuba diving. The single pane glass lens give you a wide and unobstructed field of view, while the black skirt blocks out light from the sides giving you a sharper image. The dual strap on the back conforms to my head very well and I have not had any issues with comfort. I like that there is no "frame" to this mask, instead it is one single piece of silicone that hooks directly to the strap, reducing points of failure and potential leaks. From what I have read and experienced, this mask fits a wide range of face shapes, but as with any mask I would recommend trying it in person first to make sure. The only issue I have had is sometimes (1 in 10 dives), the nose pocket can seal to my nostrils causing a squeeze, but this can be fixed by pulling the mask away briefly, and prevented by equalizing more often. I would recommend this to anyone who is looking for an upgrade.

Of all the masks I've used the Hollis M1 strikes the perfect balance between affordability, quality, and comfort. After doing the normal burning of the mask, I experienced 0 fogging.

I bought this mask after my 15 year old one finally started to leak. I did my research reading reviews and a lot of professionals use this mask for scuba diving. I used the flame method followed by white toothpaste to remove the silicone. I have to say this mask is crystal clear underwater, zero fogging, and zero leaks. I do use a couple drops of defog to make sure there wasnt any fogging but I tried with just some spit and it worked perfectly as well. I also should mention I have a facial hair and the mask still works great. I did several dives with this while on vacation and it performed like a champion.

There’s nothing i dislike about this mask.i did have to burn off some silicon on the inside and i used the pepsodent tooth paste trick and scrubbed the inside and outside of the glass 4 times. It doesn’t fog at all now. The mask is very comfortable and doesn’t leave any marks on my face. The glass is very clear , no color distortion at all. I also have an atomic venom and Tusa freedom 100 HD.this mask is every bit as good as them. The water temp this morning was 83.5 so there was no condensation on the inside of the mask. We will see how it does when the water drops into the low 70’s. Also I love the bucke system on this mask, very simple and appears to be very rugged. One other thing the mask has a very nice matte finish. I’m not fond of shiny things. Although i have heard sharks love shiny reflective thing. Reminds them of fish scales. All round its a great mask. Try one on at a dive shop to see if it fits. I have a lean face and it’s a perfect fit.

This mask is just perfect. Very comfortable under pressure at 30ft depth - exactly what is needed. I’d grade this mask as a Pro equipment.

Tried it finally in Kauai waters but just snorkeling around as I’m no dive expert whatsoever. I am now comparing this and a necessary replacement to the Cressi Panoramic which was tight and squeezed my temples cause I have a wide chubby face. Bought this cause of the many reviews and purchases of this mask even for being the older model it’s still raved reviews. So I did have to use the “lighter method’ as many mentioned but in my case I used a heat gun since I have one and much more controlled / safe which I did see the inner silicone film burn off from the glass. Looked like defrosting your car windshield in the morning. Clear view underwater with little to no distortion. Did not squeeze my head temples like the Cressi mask and give me a headache which is what Would have made or break my decision of this mask. Did not experience much fogging cause the nose really blocked my nasal passage and the seal sat right above my mustache so there was no interference there plus I had anti fog applied as well. Very minimal water came in but I’m sure cause it’s not broken in yet , still stiff and take some time to get the best adjustments for my face. I’ll resend an update after a few more trips and use. So far I’m happy with this and I’ll be donating the Cressi to a tour boats stash!

Put this mask on and you're peripheral vision is just barely reduced. Compare this to many other masks and you will be amazed, ultra low volume masks are awesome for allowing a full field of view and aren't you diving to see? Couple this with high quality glass lens and you have a fantastic mask. Price it reasonably and you have an outstanding product.

I have had several masks through the years and my last ScubaPro failed on me when I was making a deep dive, had to switch to my backup. I did more research to replace my ScubaPro and it seemed like the M1 would be a good fit for me and it was highly rated. I got it out of the box and put it up to my face and it felt like it was custom made for me. The fit is amazing. It fogs about as much as most other masks but not bad after you treat it. I don't have any cons to report, just an excellent purchase.
