the Castelli Fast Feet sock has the development and testing to back up the aerodynamic claims.

The Perfetto ROS LS is back in stunning new colors, crafted from repurposed fabrics, solidifying its place as one of Castelli's most iconic cycling jackets. Designed for professional cyclists and everyday riders, it combines advanced GORE-TEX INFINIUM™ WINDSTOPPER® technology for full wind protection and excellent breathability. With a perfect fit, lightweight feel, and impressive versatility, it performs in both dry and wet conditions. Ideal for cold weather training or unpredictable climates.

More than a decade of speed innovation and knowledge. Our fastest jersey is now faster.

Created for the hottest days when aerodynamics still matter. This jersey allows ample airflow, is quick to dry, and blocks more than 90% of UV rays on your back. A great choice for long summer rides or hot lunchtime rides in the middle of summer — or just add a base layer and it becomes a great three-season jersey.

Comfort and aerodynamics meet in the fastest, most comfortable Free Aero Race Bibshort to date.
