These are sunglasses
I have another pair of Native sunglasses, and felt that they had good optical quality and fit. The only issue I had with those was the finish (paint) is coming off around the ear pieces. The reason I went with the Throttles is that you can change the lenses, which I wanted to be able to adjust to riding conditions for mountain biking. So far, they are working out great. The fit is close, and they stay put when running or cycling. I am hoping the paint stays on over the ear pieces over time.
