Castelli’s latest version of the Velocissima Bib short updates both the interior and exterior of the bib to make them more comfortable than ever. Designed for training both indoors and on the road, the Velocissima 2 Bib Short is crafted from Castelli’s Endurance Evolution fabric to provide compressive support and effective moisture management. Staying dry is a nice benefit on a long ride, but the shorts' real strength is the compression, which helps reduce muscle fatigue to keep legs fresh beyond the second or third hour of a ride.
