Absolutely love these glasses! I workout outside daily and use them for all kinds of workouts - running, beach workouts, walking, HIIT, etc. They are super easy to wear. They're light, don't slip and comfortable. They are by far the best lower cost polarized sunglasses I've owned. I'll definitely order another pair in a different color. I also wear them daily when I'm not working out. Love the style and the color of the lenses!
