Water -resistant Nanoflex fabric
Same breathability , stretch, and warmth as our standard Thermoflex warmers
Double-sided Silicone grippers keep the warmers in place
Great in every possible condition
PERFECT FOR COLD AND WET
If thereâ€™s one failing of most warmers itâ€™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.
