Transform any pair of cycling shorts into an 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 an softer Thermal fleece fabric with improved stretch, which makes both fit and comfort exceptional. PI Dry® technology offers water-shedding performance for more warmth in wet conditions. BioViz® powerful reflective logo on the back of the calf extends to 100m in night-time conditions.
