The Castelli NanoFlex Warmers (Arm Warmer pictured above, but they produce a complete set) are truly remarkable pieces. Without getting into too much detail, a normal warmer, lycra on the outside and roubaix fleece on the inside, is treated with silicon nano-filaments to create a water repelling fabric. Rain and road spray just beads up on the outside and is then blown off by the wind. They won't keep you dry in a prolonged 3 hour downpour like a rain cape will but they work wonders in passing showers and on wet roads. I took out the knee warmers today and paired them with Castelli's also fabulous Claudio NanoFlex Thermal Bibshort. I was hesitant at first about thermal bibshorts: I just always assumed that if it was cold enough to need the fleece part, that i would inevitably need knickers or even tights. Not so, however, these bibs with embro or leg or knee warmers hits these transitional spring temperatures perfectly. More importantly, though is the fact that they are also constructed with NanoFlex, meaning that during today's halfway wet ride, they were bone dry. I know they could have taken a lot more water and stayed dry as well. I am extraordinarily happy with my full set of NanoFlex Warmers as well as my Claudio bibshorts and would highly recommend them to anyone riding in Scotland. It's impossible to always ride on dry roads in this country, you'd go out maybe twice a year. Since that is the case NanoFlex gets as many glowing stars as it needs to convince you to get them.
