This Castelli Nano Flex + Arm warmer have been in Castelli's collection for seven year, and they've 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 better while keeping all the water protection. The Castelli Nano Flex+ Arm Warmer provides more comfort due to more flexibility, and is slightly more compact.
Nano Flex fabric behaves just like Thermoflex fabric in dry conditions, but provides unbelievable water repellency when it starts to rain.
- Water-resistant and thermal breathable
- Nano Flex fabric
- Nano Light insert on back for extra strecth, bringing better fit and comfort
- Double sided silicone grippers to keep the warmers in place
