Slip on the most aerodynamic shorts from Castelli® for training rides or racing. Much like how your bike hugs every corner, these bib shorts closely follow the lines of your body like a second skin. The stretchy, near-seamless piece of fabric decreases resistance and delivers a smooth ride. Dimpled mid-thigh compression zones give your muscles the support they need to get through the last hill climb.

• Made of nylon, elastane, and polyester. Body Paint knit fabric is used to make a single, near-seamless, piece.
• X-shaped back for enhanced breathability and comfort.
• Progetto X2 Air seat pad has strategic sculpting and gel inserts to provide extra cushioning and breathability between you and your saddle.
• Intregrated leg grippers prevent ride-up.
• Sublimation-printed leg ending.
