If Castelli's Body Paint 2. 0 Women's Bib Shorts feel like they were made for pros, it's because they were. Originally developed for, and exhaustively tested by, the Garmin Cervelo team, the Body Paint is a sleek, form fitting, and moisture wicking piece of kit, comfortable enough to wear for day long rides and fast enough to take onto the race course. To eliminate chafing, Castelli cut the shorts from a single piece of fabric, eliminating the possibility of chafing seams. Breathable, wicking fabric is also finished with invisible dimples, which reduce drag think of dimpled golf balls, and has a wide leg gripper for a sleek aero fit that won't grab any air. Just as importantly, the seriously snug fit supports your muscles to reduce road vibrations, which lead to fatigue. The bibs themselves, which Castelli calls Giro2, are also made of a single strip of stretchy, non binding mesh that won't dig in or cause sweat to build up. Even more important, though, is the Progetto X2 chamois, a women's specific insert with a perforated foam layer to allow air movement and increase cooling and evaporation. The surface of the Progetto X2 is made from a seamless bacteriostatic fabric that prevents the growth of odor causing bacteria, and the padding is a combination of multi density foam and viscous inserts to take pressure off of sensitive areas.
