The Castelli Tutto Nano is a perfect bib tight for men who go out for bike rides in any weather conditions. It is the result of 10 years of intensive development done by Castelli. The new Nano Flex 3G fabric is extraordinarily warm and soft, and now also provides better protection against dampness. This makes you more resistant to cold, and also makes this bib tight suitable for use during light rainfall or for protection against splashing water. Keep in mind that it is not fully waterproof; during heavy rainfall the water-repellent qualities offer insufficient protection. The Castelli Tutto Nano long cycling tight has very few seams, so you will experience optimal comfort and a perfect fit. The mesh bib straps are breathable and do not retain moisture from light rain or sweat. This bib tight has the Kiss Air2 seat pad to keep you comfortable during long hours in the saddle. A reflective material has been added to the leg ends to increase your visibility to other road users. In addition, both leg ends have a zip, which makes putting the tight on and taking it off easier. All these features taken together make the Castelli Tutto Nano long cycling tight an ideal addition that you can use in many different weather conditions.
