The Castelli Men's Free Aero RC short 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 the Free Aero RC has been in development for the past 15 years. That's how long it's been since the original Free Aero Race short was first introduced, initially as Castelli's top-of-the-line race short. Since then it has won three Tours de France, three Giro d'Italia, one Vuelta and San Remo, but it also became the best-selling product in the history of Castelli because, simply put, these are the shorts that do everything well.
The concept is quite simple: start with the best pad made, surround it with a supportive standalone short with good muscle compression, and then remove everything else that's not absolutely necessary.
You feel Free because of further refinements to the Progetto X2 Air seamless seat pad. 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.
You feel Free because this is the first high-end short that doesn't need any sort of gripper or elastic at the end of the leg to keep the leg in place. Getting this right meant 28 prototypes and one of Castelli's most extensive test programs, and the result is the most comfortable leg ending in the Castelli catalog.
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.

I ride over 10,000 miles a year and I've tried a lot of different bike shorts. In my opinion these are the best you can buy. They are comfortable for any kind of riding and any distance. They hold up well. I'm 5'1" about 160 pounds and I wear the xl size.
I have bought this short for a number of years and had to return twice. Have ordered L previously but ended up having to go to XL and then 2XL to get a proper fit.
My weight over this time has remained the same.
