These are comfortable and they are secure (don’t leak) even without being super tight on my face. (I have tried a lot of brands and these don’t hurt my face the way others do.).
These are my second pair (I lost the first pair). They seem to work well with the H2O Interval headset (the headset sits on the strap pretty nicely).
The only negative thing I can say is that the film on the lenses is a little cloudy for my taste and has worn away some. But for me, as long as I can see the red line on the bottom of the pool, it’s fine. I’ll trade away visibility for comfort and security (they don’t leak).
