As I'm getting into biking more, I've noticed that my radarlocks are a great all around pair, but I'm not sure if they are best suited for this particular job. So what recommendations do you guys here have for the matter? I thought about upgrading my helmet to a more rugged mountain bike helmet, so with that, do I get a pair of Oakley Goggles or just stick with what I have for glasses? Curious to see what you guys use...
