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


  • 2017 Model
  • Water resistant NanoFlex fabric
  • Same breathability, stretch and warmth as the standard Thermoflex warmers
  • Great in every possible condition
  • Cam lock zip to aid fitting
  • 79g per pair
  • Fabric- 86% polyamide, 14% elastolefin
