Our Two Cents

I really like these knee guards. The hinge action is terrific. They flex easily and naturally. They make a very light sliding sound when you walk, but it’s not too noticeable. The overall quality of this product is very good too. Take the “View Larger Pictures” link above for some good shots of the knee action. We took the pictures of the armor over jeans so of course you could see them, but I would presume most folks would wear them under jeans or other motorcycle apparel.
