Castelli's Nano Flex water-repellent fabric is one of those fabrics that seems miraculous. On a dry day its as warm and breathable as normal Thermoflex fabric, but when it rains the water just runs off, thanks to the five phase nanotechology treatment.
While its not 100% waterproof, its the best solution for staying comfortable in any conditions.
On a wet day pair the NanoFlex bibshort with the NanoFlex knee or leg warmers for the same level of warmth and protection as you would get with tights.
NanoFlex fabric provides outstanding warmth and stretch, with water resistance.
Castelli make high performance technical cycling clothing. When choosing shorts or jerseys you should normally base your choice on chest and waist size. The clothing should fit snugly for aerodynamics but not restrict movement. Please refer to the charts below for fitting.
NB - you should normally pick one size smaller for armwarmers. If you use an XL jersey then chose a size L armwarmer.
We stock a range of Castelli at our retail shop in Pennyburn where you can call in to try sizing before you buy.
