Great performance and great style.

New fit. Extra comfort.

All the performance of Castelli's best jerseys, except for the aerodynamics.

The best winter bibtight for most of your winter riding. With a focus on comfort, we've used warm and soft Thermoflex fabric throughout, with carefully placed seams to minimize irritation, and the Progetto X2 Air Seamless Donna seat pad for comfort on the longest days in the saddle.

Neoprene protection. A thicker neoprene and taller cuff provide extra warmth for racing and training in wet, cold weather.

Thermoflex is luxuriously warm and stretchy in dry conditions but is not intended for wet conditions.
