      Choose Nano Flex for warmers that are great in dry conditions but
      also give some extra protection and warmth in wet conditions.
      We 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

       WHAT IT IS : Nano Flex for 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
        The Castelli Nano Flex 3G Armwarmer - Black is far and away, one of our most popular items. People can't seem to get enough of it.
