I'm not so sure. As far as I know (and I am not an expert), the only way to injure your tail bone (short of landing on a pole or a rail) is to land very hard with your midsection in a seated position (bent at the hip).<br><br>The demon shorts have padding on the butt AND on the tailbone, though only the tailbone would have had the hard plastic padding.
I think that the OP might have hurt his tailbone no matter what he was wearing.
Anything with enough padding to absorb the energy from an impact hard enough to bruise his tailbone through these shorts
would probably be waaaaaay bulky.
I wasn't there, so its hard to say. I have crash landed pretty hard while wearing in the same Demon shorts without sustaining injury to the areas they protect.
