With the Competizione Bib Shorts, pro-level Castelli quality need not come at a pro-level price tag. The Competizione features much of the same technology as their higher-end offerings, like a KISS Air2 insert and Giro4 leg grippers, making it comfortable for long and short rides alike. The main panels use Castelli's Vortex fabric for optimal breathability and comfort, while the bibs are a more open mesh to ventilate well beneath a jersey. Castelli uses a tighter Lycra for better compression, stretch, and rebound, where there's more movement when pedaling. The KISS Air2 insert's perforated padding and seamless upper keeps cool air moving through the short to ensure your comfort on the bike.
