I’ve been fighting with leaking goggles my whole life, I figured it was just the shape of my eye socket that kept them leaking, I’d have to tighten the straps and create suction to stop the leaks and then I would have rings around my eyes for hours. I’m so impressed with these goggles, not only are they comfortable but also so clear in the water, no leaks, no over tightening required. Expensive, yes, but for the quality and comfort you get it is well worth it. The only thing I advise is get the anti-fog spray, even though they have an anti-fog coating they did fog up after several laps.
