The Evolution Of Innovation

The Castelli Women's Free Aero RC Bibshorts are the perfect mix of comfort and speed. Engineered for top-level racing, which also makes it supremely comfortable for every ride and rider. The Free Aero RC Bibshort is Castelli's top race short, which also means that it's insanely comfortable even if you never pin on a number.

It's fair to say that Castelli has been working on this short for the past 15 years. That's how long it's been since the original Free Aero Race Bibshort was first introduced, initially as the top-of-the-line race short in their catalog. The various versions of the Free have dressed all of Castelli's pro women's teams over this time, and it also became the best-selling women's short in the history of the storied Italian brand.

The concept is quite simple: start with the best pad made, surround it with a supportive short with good muscle compression, and then remove everything else that's not absolutely necessary.

You feel Free thanks to the reduced number of panels and the reduced number of seams. In fact, the short portion has just 5 panels compared to 10 in the previous generation.

You feel Free because of further refinements to the Progetto X2 Air seamless chamois. The two densities of foam plus the gel pads provide progressive damping, while the separate Skin Care Layer is soft and stretchy to move with your skin.

The Forza 2 fabric has 32% Lycra with a high modulus for exceptional muscle support and just the right amount of compression. There's reflective piping on the back. And all logos are either stitched or embossed for durability.
