From rough gravel rides to smooth road training sessions, the Castelli Unlimited Cargo Bib Short is engineered to keep us comfortable and performing at our best. The stretchy Affinity Pro Lycra fabric moves with us as we get in and out of the saddle, while the Kiss Air² Donna seat pad delivers the seated comfort we desire for rides of any length. For optimal storage, each side of the shorts features a cargo-style side pocket with a top flap to keep our phones, tools, and snacks secure while we ride.
