Review on Frameless Scuba Diving And Snorkeling Mask: Tilos Excel For Free Diving by Victor Pinckney

I have not used this mask yet, having just received it. I was very much looking forward to it since my snorkel habits, for better or worse include wanting to see what I am heading toward as well as what is below and to do this, especially in shallower waters, I find I am constantly bending my neck back and because of the position end up with slight nausea and/or neck ache. This mask looked like it would help a lot and having put it on I can see that it would. It's a fine mask but unfortunately is not well designed for narrow faces such as mine. My test for masks is to put them on without using the strap and see how well they stay on. by the force of natural suction alone. Any mask that does not pass this test will leak in my experience, unless the strap is so tight it is uncomfortable. I am sorry to report the Tilos frameless failed this test. But that is only because it is designed for a fuller face. Otherwise i can tell I would have loved it as the field of view upwards is excellent.
