Really pleased with how good these bib shorts are. They’re a good fit & I’ve done 3 rides of 60 miles in comfort. If it helps I’m 5’6”, 68 kg, 40” chest & the xl are a nice fit.
Product Details
Castelli Tutto Nano Bib Short
Castelli’s Tutto Nano Bib Short should be a staple of every keen cyclist’s wardrobe. It provides the same excellent comfort and performance as Castelli’s other shorts, with the addition of extra warmth and protection against inclement weather conditions. A KISS Air 2 pad provides plush, day-long cushioning with the broad leg grippers spreading any pressure and keeping them in place.
Tutto Nano Bib Short Design
The 3G Nano Flex fabric is has a light, brushed inner for insulation, and a water repellent treatment which prevents rain or road spray from soaking into the material. As there is no membrane involved, the short is not waterproof, but the lack of membrane also means that it is just as comfy, breathable and unrestrictive as any other short. This warmer, denser construction also means that it is more wind-resistant than most shorts.
The Tutto Nano Bib Short is perfect for pairing with Castelli’s Nano Flex 3G leg warmers on cool, damp autumn and spring days, or wearing under a pair of long tights in deep winter conditions for maximum insulation.

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.

Extra length of short with thicker water repellant type coating. Intend to use with the nano leg warmers in the autumn/winter/spring. Good quality. 34inch waist, 193CM and went with the Large as per the size chart. Good fit.
