PERFECT FOR COLD AND WET
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 Castelli Nanoflex Arm Warmers are perfect for riding in conditions that are both cold and wet. Nanoflex is a proprietary Castelli fabric. Castelli begin with super-warm and ultra-stretchy Thermoflex fabric, used in many of their winter garments, and then coated 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.
- Water resistant nanoflex fabric
- Same breathability , stretch, and warmth as Thermoflex warmers
- Double-sided Silicone grippers keep the warmers in place
- Great in every possible condition
