CASTELLI NANOFLEX Leg Warmers Black

If there’s one failing of most warmers it’s that they absorb water like a sponge. On rainy days they end up waterlogged and providing compromised warmth. 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.
