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. The bibs are finished with a raw-edge hem to prevent any pinching or constricting at the thigh. Vertical silicone strips along the interior of the hem keep the short in place. The Velocissima 2 uses an updated chamois, a women's-specific KISS Air2, which is Castelli's preferred long-distance insert.
