Nano Flex All-Condition Warmers

Choose Nano Flex for warmers that are 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.

  • Water-repellent thermal and breathable Nano Flex fabric
  • Flat-lock stitching with single seam
  • Double-sided silicone grippers to keep warmers in place
