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. - Thermal fleece fabric with water-shedding - PI Dry technology for all-weather performance made with anatomic construction eliminates bunching through your full range of motion - Plush, wide elastic binding with silicone gripper for a stay-up fit - Anatomic left- and right-specific fit - BioViz reflective elements for low-light visibility - Unisex sizing - 56% recycled nylon, 30% polyester, 14% Lycra elastane - Made in Vietnam
