MORE FLEX, MORE NANO
Castelli's Nano Flex warmers have been in their collection for seven years, and they’ve finally found a way to improve them. The’ve 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.
- Water-resistant thermal and breathable 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
