The rain or shine bibtight

Better in cold and dry and better in wet conditions, the new Nano Flex Xtra Dry fabric makes the Castelli NanoFlex Pro 2 Bibtight your most technical tight. The base fabric is a tighter-knit double-layer construction, and the water repellency treatment is improved to provide even more protection. Castelli is not quite there yet on the goal of bringing full waterproofness to a non-membrane fabric, but this is a significant improvement in making your foul-weather riding much more comfortable. It will also be your go-to tight for dry conditions, though. It's a no-compromise piece for all your cool-weather riding.

It's not just about the fabric.

This is a serious training tight, so it gets our Progetto X2 Air Seamless Donna seat pad. For total protection in the high-splash area of the inner leg, Castelli uses a fully reflective waterproof fabric 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.
