Castelli Nano Flex 2 Mens Bib Tight - Black

In dry conditions the Nano Flex fabric is stretchy, breathable and warm thanks to its softly fleeced inner face. But in wet conditions the nanotechnology water-repellent surface keeps much of the moisture at bay. There is no membrane to block breathability, though, so in harder rain or on longer rides some moisture will come through. But that’s when this fabric is at its best: it never feels waterlogged, it almost feels dry on your legs, and best of all it continues to keep you warm. If you’re going to do serious rain riding, you should look to our Nano Flex Pro Bibtight, or even the Tempesta Pant, but for lighter rain, warmer temps or wet roads this will be ideal.

One of the cardinal rules of dressing for cycling is that your tights or leg warmers go inside your booties. Nano flex changes that. When it's raining put the tights or warmers over the booties to shed rain to the outside of the bootie and help keep your feet dry.

Train through anything

Castelli initially developed the nano flex tights to help you get through the occasional rainy day of training. But you asked for more so here it is: the extreme-duty nano flex bibtight. By putting an extra layer over the thighs knees and bum they were able to significantly increase the rain protection while also blocking a bit more wind. The lower inner leg has been made to be completely waterproof since this was usually the first area to soak through with our nano flex tights. And because these tights are going to see heavier use the seat pad has also been upgraded to the Progetto x2 air so you're ready for long rides with a high probability of rain.
