If my knees could talk, it would say "You're Awesome". Because it is that awesome. It is so awesome that the definition of the word was defined by this product.
Any-who, the kneepads does a spectacular job at preventing my knees from exploding from the awesomeness of my riding. It is rather comfortable with liners on, however it is a bit torturous without (especially when bending your knees while taking a big deuce). But if you can stand through having elastic straps cutting circulation off your bare skin, you are cool in my book.
Most of the time, I don't even realize I'm wearing them. They are so versatile that I wear them everyday to school, to the supermarket and even wedding receptions. You never know when someone might take a hatchet or a chainsaw and cut up your knees, but when it does happen, you will be more than prepared.
It's like being Iron Man... only on your knees though. If someone shot you, you'd probably be seriously injured (unless they shot you in the knees).
