More flex, more nano

Castelli's Nano Flex warmers have been in their collection for seven years, and they have finally found a way to improve them. They have added an insert on the back in Nano Light fabric to help them bend around your elbow or knee better while keeping all the water protection. More comfort due to more flexibility, and in a slightly more compact package.

Key Features:

Nano Flex fabric

Nano Light insert on back for extra stretch, bringing better fit and comfort

Double-sided silicone grippers to keep the warmers in place

Ankle zips (leg warmers)
