SIXS original carbon underwear' sounds like something developed for Batman, but it's not just more carbon fibre gimmickry. SIXS have been very smart in their use of carbon. During the fabric production carbon is woven in with the Polypropylene to produce the SIXS patented fabric.

SIXS Carbon underwear can be worn on the bike (and off) for hours without stinking, unlike other base-layers.
