KTM PowerWear's got something similar. Or maybe it isn't so similar Considered it for offroad.

I looked into purchasing knee braces after I fractured my knee and tore all my knee ligaments. I tried several different manufactures and turns out none of them really fit comfortably. I guess I'm a wee bit too bow legged. I ended up going with Dainese Knee V Knee Protection for the dirt. I wear them for street also, better than nothing.

I came across these people recently. Products look good and pricing is keen...
