I purchased a couple pairs of these glasses, because I tend to lose and/or break sunglasses frequently when running and/or biking.  These glasses fit great, feel great on and have become my favorite glasses when biking because they force wind away from my eyes in cold weather, which prevents my eyes from watering. They fog a bit when I run (although not nearly as much as most others), I have never found a pair that doesn't because of how glasses sit on the bridge of my nose. The price is right, the features are great! These have quickly become my favorit sunglasses when active outdoors.
