It is not waterproof. It was tested by two different people and no matter how tightly you tighten the straps, after a little while the mask "takes in" water.

I bought this mask for spearfishing, I thought I would try something different. First of all, the mask is not watertight, it seems to fit perfectly on the face but it still fogs up a lot, whether you breathe through your body or through your nose. Conclusion: it's better to buy the classic ones!

I bought it with some concerns after seeing comments about the size or the quality of the mask.... I have to say the following after testing it in several swims this year. Firstly, in terms of size, I don't think it's ideal for children, but the fit was very good for me, although in general, when putting it on, it requires proper placement. I mean, you have to make sure it is applied well because if not, some drops can enter... nothing terrible, but it requires attention. I wanted it so that I could see more comfortably underwater, and it delivered. In terms of breathing, it never fogged up, and you could stay underwater for a long time. It did its job very well, and I recommend it instead of regular masks or masks with a separate breathing tube....

After 2 - 3 uses, simple swimming on the surface, I am quite satisfied. I will compare it to a similar one I had bought from Lidl, it lacks peripheral vision, neither of them fog up, with the mask from Lidl, I breathe better (without the specific one lacking, I say it as a feeling), they fit well on the face. The secret is to "embrace" the chin well so that they don't fog up. In a dive (4 - 5 meters), neither of the 2 let water pass through.

The worst plastic they sent me the wrong size, it leaked water everywhere after just one use, do not buy it, the worst thing, not recommended
