I swam a 7km open water swim with these, and tried them for practice before. They never fogged up, they stay in place better than any other goggles. Putting them onI thought they would be too flat close to the face, but once in the water they feel great. I loved the extra peripheral vision. They feel bright, almost yellow lense when put. No glare. I will be saving these for important open water swims. The bonus pouch is much appreciated to avoid scratching them.
