Castelli's Nanoflex arm warmers are a testament to the brand's position as an innovative market-leader. Crafted from intelligent Nanoflex fabric, these arm warmers bear all the cooling properties of a Thermoflex fabric in dry conditions to ensure you remain fresh and ventilated, yet when it begins to rain the NanoFlex fabric then transforms to show its excellent hydrophobic qualities which repel water to keep you cool and dry. Double-sided silicone grippers keep these cycling essentials in place throughout your journey and the arm warmers are finished with the signature Castelli branding to the forearm. - L.R.
