Castelli Nanoflex 3G Legwarmers

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.

• Flat-lock stitching with single seam
