NanoClear™ Flex Swim Goggles Smoke - (Green)

I like the wide field of view and less rapid fogging with these goggles, but they still leave a mark around my eyes that takes a few hours to disappear. I have yet to see if it helps out with pressure headaches I intermittently get from other goggles. The flex goggles didn’t leave a mark on my face, but did leak intermittently while I swam (think from the inside corner near my nose). I do like the colors and the look of both styles. It would be nice to have a goggle for strong outdoor light/sun for midday practices. I only saw moderate to low sun protection lens options.

I absolutely love these. I've had them for 2 weeks now and as advertised - no fog. Interestingly, the eye cups feel like they fit tight out of the water but that's deceptive. Once in the water they may be the lightest, most comfortable goggle that I've had so far. I'm using them for early morning open water (lake) swimming. The only improvement would be polarized lenses to cut back on the glare during sunrise.

These goggles are very comfortable and are leak free but I have not had success with “fog free”. I have followed the directions/suggestions on how to keep the fog from forming but they literally fog up the moment I put them over my eyes. Granted, not as much as other goggles, but certainly more than I expect them to. I was hoping these would be a game changer but so far they are not.
