Why We Love It
Outstanding stretch, luxuriously soft, and warm. This arm warmer will keep you comfortable on your next chilly ride.
Where We Use It
Perfect for those cold weather, high intensity rides.
If you don't need the extra wet weather protection of Nano Flex, or if you've always been happy with traditional warmers, you'll find that Castelli's Thermoflex warmers offer the softest, most luxurious fabric combined with careful attention to construction details.
