These are Castelli leg warmers. Size: M Fleece-lined NANO FLEX I purchased these used, having worn them twice, but I'm selling them because I haven't had the opportunity to use them. I believe there are no noticeable stains or scratches. Please check the images for the condition. Official description: 8°C - 20°C / 46°F - 68°F Fit: Regular fit Castelli's specially developed Nano Flex 3G material, the result of years of testing, is a magical fabric that combines water repellency, warmth, and breathability. Flat seams for a comfortable feel against the skin. Double-elastic silicone grippers prevent slippage. Used frequently by top professional riders in actual races and training.
