I got these for working outside in the bleak midwinter. The wind is very strong in PA and a lot of my work would be done at night or with cloud-cover so sunglasses (Also a pair of KDs) were out. I had a problem. How did I keep the wind out of my eyes while I worked? I made a brief list of who else had to deal with that problem. World War I flying aces, 1950s F1 car racers, motorcycle riders. Bingo Boingo. What do they wear? KDs.

I can say the wind never bothered me. The glasses fit snugly under my beanie and let me keep my eyes open as I worked. I can't recommend them for bikers as I don't ride myself, but for somebody who works outside and needed a way to deal with the wind that was more manageable than goggles, these are exactly what the doctor ordered.
