Perfect for cold and wet: The Nanoflex warmers are perfect for riding in conditions that are both cold and wet. Nanoflex is a proprietary Castelli fabric. We begin with with our super-warm and ultra-stretchy Thermoflex fabric, used in many of our winter garments, and then we coat the outside with ultra-tiny nanofilaments that cause raindrops to run off the fabric without soaking through. Despite its water-resistant finish, Nanoflex fabric remains highly breathable, keeping you comfortable in almost any conditions.
