I’m a live and let live kind of guy. If you log a significant amount of miles, then you need to think safety. Do you wear a helmet? Good. Do you tell your friends that you only shave your legs because it helps road rash treatment? Then look at this. It is a great idea and for 20 bucks a no brainer. That is why you wear a helmet right? To save your brain to make these kind of decisions.
I only wish my brain thought of it first.
