has anyone wore or crashed in Kevlar jeans? lige the Teknic Rage?

 

I lowsided at about 25 mph in a pair of draggin' jeans (a 180-degreeon-ramp posted at 10 mph) and they held up fine. I'msure my knee would have been a lot more scraped up without the kevlar,but I don't think I would want to testthem at much higher speeds.
