Shorts so light and comfortable, you won't even notice they're there. Castelli's Body Paint 2.0 Bib Shorts use Body Paint engineered fabric for a completely seamless, supportive fit. Variable knit structure means that all the components of a traditional short are included in a single piece of fabric. A mesh lower back, integrated cuffs, and aero dimpled legs offer pro level performance. The Progetto X2 chamois is the equipment of choice for pros and enthusiasts alike, with four-way-stretch antibacterial fabric, multi-density, perforated padding for increased air flow and all day comfort.
