Heh, I've been down twice now -- once pretty substantially (60mph lowside on the DC Beltway) and I can tell you from experience: denim doesn't do a d*mn thing. It's invisible to pavement. Leather good, cotton bad.
The last time, all the parts fo me in leather were completely unscathed. My knees -- I was weaering jeans -- got all banged up, and I still have scars. I still ride with jeans, mind you... but if I hadn't been wearing a leather jacket, boots and gloves, I'd be a sausage creature for sure.
