adiwi Full Face Snorkeling Mask Snorkel Diving Mask 180° View Ear Pressure Equalisation Anti-Fog Anti-Leak Clip-on Straps Action Camera Mount UNIVERSAL ONE SIZE Fits most ADULTS and KIDS after 12

I bought this mask because my previous one was using the same air flow for in and out so wasn't CO2 free and it was fogging a lot. This mask solved the fogging issue. Seriously crystal clear vision with no fogging whatsoever.If you have a small face you might consider to give it go.Unfortunately I can't use it more than 20-30 minutes because "one size fits" all doesn't work. The bottom part is pulling the nose rubber and it digs into my nose a lot. I can compensate a little bit by keeping my mouth shut and breathing only through the nose. If I open the mouth it's kinda hurt a lot, but sometime I might want to inhale a bit more so I have to do it. I would definitely buy this mask if they would have a bigger size. Currently I will have to throw it away ( I don't think I am eligible for a return/refund) and I will search for a bigger one.Later edit: I was able to return the mask so good customer service.

Don’t normally write reviews but feel the problem with this mask needs to flagged.I have a open open face snorkel already by another brand which has been brilliant but getting used a lot, like every weekend as I live in Fiji. So decided to buy this one to replace it. It looks good straight out the pack, well presented and well made etc. But the key problem is the one size fits all. It doesn’t. I have a normal medium sized face and this is very small on me, I can’t open my mouth fully nor breathe through my nose. On my current mask which is medium sized it all works great, held along side each other you can see how small this one is. See pics for size reference. So this really doesn’t work for me and thus is money wasted. If you have a small face, it maybe fine but beyond that the concept of one size fits is massively flawed.

I have not used this mask in the water yet but was very pleased when I received it. It seems good quality and appears to fit my face better than my old mask (another brand) which tends to leak. I also really like the clip at the back.

I loved an expirience of snurkling what this mask gives. Handy and easy to use. Earplugs are connected and will not fall off to compare to my other one. But after about 15 min gives you uncomfortable feeling on cheekbones and leaves marks for about an hour or so.

Bought this use in The Maldives where there is an abundance of tropical fish , so really important that it was going to work well. It was brilliant and jumping in off the boat from 2m up , no problems , the snorkel park shuts off and once your on top of the water again it opens straightaway and your breathing again . Comes with built in ear plugs and they also work well.

HiI agree with the first review. This mask is way too small for an adult person. I tried it on Seyschells but water was constantly flooding this mask. I ended up using my old mask.It looks good and the quality is good too but unfortunately not for me so yes it was a waste of money.

It does leak abut and will need more adjustment by me and the mask hurts the cheeks after a while

The biggest downside of these snorkeling masks is that the strap that's used to secure the mask to your head gets loose really easily which lets water enter inside (slowly but surely). It's also hard to breath in it after 20 minutes of usage. The gopro mount is rubbish, the footage is practically unusable because of the location of the mount.On the bright side, the viewing angles are awesome.
