Jersey Fit Guide
While everyone wants their bib-shorts to fit close to the body to perform at their best, how a jersey should fit is a very personal matter. When we develop our collection’s tops we do it working on three different fits that define every line within the collection; SLEEK, SLIM, CLASSIC. Have a look at our jersey fit guide below to understand how the different fits work! Remember to check the FIT type on the product page and choose your size according to how you want it to fit on your body!

Sleek "Aero" Fit
Skintight fit, shorter on the front and elongated in the back. Developed with riding position in mind to maximize aerodynamic properties. This is the fit that our pro athletes use for racing. If you like a jersey of our Aero Light range but you prefer a less tight fit, we suggest choosing one size larger.

Slim Fit
Form fitting jersey. Remains close to the body minimizing wind resistance in the saddle. This is the fit that defines Santini. Incredibly versatile as it gives you a sleek profile while maintaining incredible comfort throughout your ride.

Classic Fit
Regular fitting jersey. Soft on the body for those who look for a more classic fit. If you like a jersey of our Everyday-comfort range but you prefer a tighter fit, we suggest choosing one size smaller.
