There is a company over here called Draggin Jeans, they make jeans and pants with Kevlar lining for motorcycle riders. (They are an alternative to leathers, but look like normal pants.)

They once made a Kevlar bikini (for promotional use). I wonder if they would make a Kevlar kilt!? It would seem a good idea for their promo tours, a pretty girl in a Kevlar bikini to attract the men, and a handsome young man in a Kevlar kilt to attract the women. I might suggest it to them!

(Although I wouldn't want to put a Kevlar kilt through this, their normal demonstration!)
