These sunglasses are amazing. But you have to get the polarized ones to get the most out of them especially if you're going to be on the water, snow, or driving with wet pavement. They are extremely light and stay placed well on your face when running or outdoor activities. I have had mine for 2 summers now and they have cracked on the sides (they have a lifetime warranty so I hope they get replaced) , but I use them for wildland firefighting, and have taken a shot with a volleyball to the face, they lasted still longer then all others I have gone through. Great visibility A+ comfort
