Castelli Nanoflex+ Armwarmer
HOW DO THEY DO THAT?
We always strive for total performance and total innovation, but sometimes we surprise ourselves. This Nano Flex fabric behaves just like our Thermoflex fabric in dry conditions, but then provides unbelievable water repellency when it starts raining. We don’t claim that it’s fully waterproof, but it’s the most effective product we’ve ever made for keeping you comfortable in all conditions. It’s just short of a miracle.
