This mask took a little time to get used to it's character. Out of the box the fit was almost perfect. I have a well trimmed beard and mustache and it took some time before I had adjusted the tightness correctly. I have swum for over 10 years and this is the first time doing so with this kind of a full-face mask and snorkel system. I tightened both sides of the adjusting straps before getting a fit that is tight enough for preventing water from entering the free breathing area. Sometimes, if you accidentally turn your head slightly too far to the side, the water-stop feature closes preventing air from being able to pass freely inside. This surprised me at first and it took a little time before realizing the primary objective is keeping the head still in the water. Once I mastered that, the mask worked perfectly allowing good clear viewing and normal breathing. Unable to think of a better solution, I fitted the mask over my face while also removing my swim cap. This improves the fit and the watertight aspect of it was not compromised. I swam a mile before switching over to this mask, and continued with my 3 mile swim. It was comfortable once it was tight enough. For some reason, swimming while breathing freely under water, felt harder than with a smaller facemask design. I am confident that with continued practice, this will change as I feel more and more comfortable using this item. After completing 1250 yards with it, I switched back to another mask design. I will increase the distance with it daily and am confident that before long, it will feel very comfortable and I will probably not swim without it. A+
