Boxer Shorts made out of CarbonX.

CarbonX and Nomex are very simliar in that they are both materials that are designed to keep you protected should you get involved in a fire. They are also designed to keep you cool and dry. What makes CarbonX different is that it wicks away moisture much better than Nomex does. It's also virtually flame proof, as shown by the picture above.
