CASTELLI Nano Flex 3G arm warmers

Armwarmer.

Nano Flex for the ultimate warmer:

warm and comfortable in dry conditions, water repellent in damp conditions, and still warm in extreme conditions.

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.

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.

Water-repellent thermal and breathable Nano Flex fabric.

Flat-lock stitching with single seam.

Double-sided silicone grippers to keep warmers in place.
