Transform any pair of cycling shorts into a knicker with these super versatile knee warmers. A general rule is to keep knees covered up to 60 degrees, which means these warmers could see action all year long. Our latest warmers feature a new, softer Thermal fleece fabric with improved stretch, which makes both fit and comfort exceptional. But our PI Dry® technology is what really sets these warmers apart, offering permanent water-shedding performance for more warmth in wet conditions. A BioViz® logo on the back of the calf adds reflectivity in low-light conditions.
