Castelli NanoFlex Leg Warmer 

Castelli always strive for total performance and total innovation, but sometimes they surprise themselves. This NanoFlex fabric behaves just like their Thermoflex fabric in dry conditions, but then provides unbelievable water repellence when it starts raining. We don’t claim that it’s fully waterproof, but it’s the most effective thing we’ve ever made for keeping you comfortable in all conditions. It’s just barely short of a miracle. 

  • Water-resistant Nanoflex fabric
  • Same breathability , stretch, and warmth as our standard Thermoflex warmers
  • Double-sided Silicone grippers keep the warmers in place
  • Ankle zips
  • Great in every possible condition
