On warmer winter days or on cool early morning spring and fall rides, the Castelli Nano Flex 3G Leg Warmers protect you well from the elements, be it wind or rain. The 3G fabric is insulating yet breathable with a soft feel, and the warmers are compact enough to stash in a jersey pocket if things start to heat up. The rear ankle zipper can be adjusted to fit while making them easy to put on and take off. Gripping elastic around the top prevents any slipping midway through.
