I bought these on a whim. I commute by bicycle. That being said, I am always looking to save space and weight. Having all three lenses in a lightweight case is outstanding. I leave early in the morning. The contrast orange lenses are great for that setting. I "ride off into the sunset" in the return trip. The smoke lenses cover that. The clear are quite effective in the rain.  For the money I can't imagine looking any further than these. If they last, they will retroactively earn that final star.
