Castelli Nano Flex Knee Warmer Sleeves

The crisp morning air might whisper warnings, but your ambition for that long climb doesn't have to wait for the sun. Castelli's Nano Flex Knee Warmer Sleeves are engineered for those nuanced days, where the mercury dips just enough to warrant a layer, yet too much for full leg coverage. Crafted with the renowned Nano Flex fabric, these sleeves offer a masterful blend of insulating warmth, surprising breathability, and a revolutionary water-repellent finish that shrugs off road spray and light drizzles without compromise. When the climb warms up or the clouds break, they pack down effortlessly into a jersey pocket, ready to redeploy for the next cool descent or unexpected turn in the weather, making them an indispensable ally for unpredictable routes and epic rides.
