From the Pinarello website:
ANTISTATIC
Conductive carbon fibers absorb and dissipate electrical charges created by the body
Oddly enough, this seems to be a thing when I Googled it so for some it might be a wanted feature.
BACTERIOSTATIC
Carbon blocks the proliferation of bacteria by acting on the cell wall of microorganisms
Not sure if this is really a thing unless people don't wash their clothes often...
THERMOREGULATING
Carbon is an excellent conductor of heat, thus keeping the body at an ideal temperature
A good thing, if it works in any meaningful way that can be felt vs other materials.
Jury is out then! We shall see. I'm not one for disparaging something until I've personally tested it or seen substantial evidence against from others. Do agree that this does smack of Marketing Magic though rather than a truly wondrous thing.
Certainly, while this 9% of Carbonio weave is a Marketing catch, the RRP of these clothes isn't higher than the high-end of any top manufacturer, such as Castelli, Assos etc.
I normally wait for Sales but in this case, since I have the vanishing small marginal gains Dogma F bike, I'm splurging on the 'matching' kit now for Summer.
