Castelli Nano Flex Pro Race Bib Short
With the additional protection over the knees that the Castelli Nano Flex Pro Race Bib Short provides, it's a great choice for winter training and cold race days. Nano Flex 3G has been used for the main fabric; it's warm, stretchy and supportive, while effectively repelling light rain and road spray. A soft brushed inner is super comfortable and helps to retain body heat and, engineered with reduced seams, the ingress of rain is further prevented.
The bib straps are light and breathable, supporting the short without feeling restrictive, and a Progetto X2 Air seamless seat pad takes care of protection in the saddle.

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.
A. Chest: Holding the tape horizontally, measure under your armpits with your arms relaxed at your sides, around the fullest part of your chest.
B. Waist: Holding the tape horizontally, measure around your natural waistline, across the belly button, keeping the tape a bit loose.
C. Hips: Holding the tape horizontally, measure around the largest part of your hips, keeping the feet close together.
D. Inseam: Measure from the crotch to the base of the ankle bone
Reviews
I had nano flex leg warmers worn with regular shorts and was always impressed by how they kept you warm in showers, as opposed to the regular shorts. Adding the nano flex shorts I have headed out with confidence into our English damp weather. The water beads, then leaves! And the unfinished lack of gripper has been seamless so far.

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.
