I love to be near, on, in, and under the water
I use these to lap swim sometimes instead of traditional goggles. I also use them to rage on my 2 seater Seadoo and my standup Jetski. High velocity spray to the face all day with no problems. I have tinted and clear, and now I want polarized mirrors for the coming race season.
I keep a pair in my gear bag for:
-racing in really foul weather
-to go under to clear fouled lines
-to find items lost over the side in shallow water
-to treasure skin dive a mooring field during an AP.
I always apply anti fog to goggles and masks before every use and never have any visibility issues.
You also have to wear them fairly tight and press them to get a good seal for under water. Above water can be less snug.
I think they are pretty cool looking too, like weird sunglasses. A future cool trend? Soon to be on the face of every foiler, lol.
