Castelli Nano Flex 3G Armwarmer Black / S Apparel - Apparel Accessories - Warmers - Arm

Nano Flex 3G Armwarmer


Great in dry conditions but also give some extra protection and warmth in wet conditions.

Castelli invented the category of water-protective thermal fabrics, and Castelli's proprietary Nano Flex is often imitated but never equaled. No compromises for any conditions.  Nano Flex is the ultimate warmer: warm and comfortable in dry conditions, water repellent in damp conditions, and still warm in extreme conditions.

  • Water-repellent thermal and breathable Nano Flex fabric.
  • Flat-lock stitching with single seam.
  • Double-sided silicone grippers to keep warmers in place.
  • 8°-20°C / 46°-68°F
