Okay, so it's not really motorcycle gear we found on eBay this time. But this would make an awesome addition to your riding apparel anyway.
Wear these puppies and you'll not only be safer- you'll feel faster too! Reflective shiny stuff lights up like crazy when lights hit it at night. Straps on to pant cuffs or around boots with space-age Velcro magicness. Be the first on your block to have a pair!
Some claim these are really intended for bicycle riders to keep their trousers out of a greasy chain. I suppose you could try it.
