Product Details
Castelli Body Paint 4.X Speed Suit
The fastest in Castelli's range, the Body Paint 4.X Speed Suit sits at WorldTour level so you can be sure of the marginal gains it produces. Extensive CFD analysis, wind tunnel testing and input from pro riders has gone into the development of this garment, and the use of smooth, slippery fabrics, with reduced seams significantly reduce drag.
A Progetto X² Air Seamless seat pad effectively absorbs shock, placing enough padding between rider and saddle for good cushioning that won't feel overly bulky. The pad is designed to breathe too, for a fresher feel, and moves with the body, both in and out of the saddle.
Extra long legs and sleeves with grip tape stabilise the suit without oversqueezing, and the design includes a flat, no-sew race number window so there's no need to pin on a number that may flap around.

If you're unfamiliar with your Castelli size, we recommend you go up one size to obtain the best fit possible. Note that you do not need to size up for jackets or vests; please select your normal jersey size.
Castelli clothing is designed for its intended use and should be comfortable when on your bike in a riding position. Your garment should be snug to provide you with moisture-wicking capabilities, as an aerodynamic aid and prevent any fabric from flapping in the wind.
If you require any advice on Castelli sizing, please do not hesitate to contact us.

About Castelli
At the front since 1876.
Castelli has been at the front of cycling apparel since 1876, founded in Milan as the original maker of pro race kit. From the first cycling jerseys to today's WorldTour-proven aero garments, the brand has spent nearly 150 years putting innovation onto the backs of the fastest riders in the world.
Castelli outfitted the first organised cycling teams in Italy and has been a constant presence in the pro peloton ever since. The Scorpion logo appears on more WorldTour podiums than almost any other apparel mark.
