The Castelli Nano Flex Pro 2 Bib Tight is built using Castelli's Nano Flex Xtra Dry fabric. Eight years have passed since Castelli pioneered nanotechnology coatings in cycling clothing to provide a higher level of water protection without sacrificing breathability or stretch. They never stopped working on improving the fabric, and after numerous small improvements they are ready with the first major update. The base fabric is a tighter-knit double-layer construction, and the water repellency treatment is improved to offer even more protection. This will also be your go-to tight for dry conditions. It's a no-compromise piece for all your cool-weather riding. It's not just about the fabric, though. This is a serious training tight, so it gets Castelli's Progetto X2 Air Seamless seat pad. For total protection in the high-splash area of the inner leg, a fully reflective waterproof fabric is used that adds a high degree of nighttime safety to this tight. The tight is constructed with the bare minimum of seaming, which helps keep the rain out and also makes it more comfortable. This is the best all-around tight that Castelli knows how to make with today's technology. Temp Rating: 0°-12°C / 32°-54°F.

Note: Please check sizing chart before ordering, Castelli clothing runs small, so we recommend ordering at least one size larger than what you might normally wear.
