It took me a while to spend the money, but since the day I did, I wear NO OTHER GLASSES! I chose the Man-o'-War style due to the removable side shields and the way they fit my face. I use them from the lake to the highway. I usually keep the side shields on but they clip on and off easily and after 2 ½ years they are still tight. I am pretty rough on them and I still have no scratches on the lenses. With a lifetime warranty they can't be beat in my opinion.
