No concussion!

Had a skating crash yesterday and landed hard on the back of my head. The RSRmicro straps broke free and cushioned my head so I got a goose egg on my head but no concussion! I am ordering a new one so I can get back to practice.

Cool off bike look

Mine are brown frames with brown-green lenses. They remind me of the Spinair with a hint of aviator. Lightweight. Many compliments!

Crystal Clear

I like the wide field of vision and they are very high quality. Crystal clear lenses. They are bit wider fit vs the non-prescription Cutline pair that I own given less lens curvature of the prescription version.
