Castelli looked to its earlier designs while developing its latest bib shorts masterpiece, seeking to improve upon its impressive Body Paint with a lighter, faster, and more comfortable platform. We can't imagine it was an easy task, but the resulting men's Mondiale Bib Shorts confidently establish a name atop the monument of Castelli's other impressive offerings. The shorts combine new fabric and pared down construction for shorts that feel as close as possible to wearing nothing at all. A major theme for Castelli when constructing the Mondiales was to create shorts that wearers would be able to forget they had on for logging long hours on the roads free of clothing related distractions. The all new Cinquanta fabric of the body is the key to this disappearing act.
