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 DryA(R) technology is what really sets these warmers apart, offering permanent water-shedding performance for more warmth in wet conditions. A BioVizA(R) logo on the back of the calf adds reflectivity in low-light conditions.Thermal fleece fabric with water-sheddingPI Dry(TM) technology for all-weather performance made with anatomic construction eliminates bunching through your full range of motionPlush wide elastic binding with silicone gripper for a stay-up fitAnatomic left and right specific fitBioVizA(R) reflective elements for low-light visibilityUnisex sizing56% recycled nylon, 30% polyester, 14% LYCRAA(R) elastane Made in Vietnam USE SIMPLE DETERGENTS WITH NO ADDITIVES Never use detergents with fabric softeners, perfumes or any additive type product. The general rule of thumb is the simpler the better. Many detergents with additives leave "surfactants" behind on a fabric's fibers that inhibit the technical performance. Typically the best detergents to use will have "Clear" or "Free" in their names. Don't pour the detergent directly onto the clothing, put it in the washer first, when you start the water. If something is not functionally working, but is not dirty, try rinsing it twice in warm to hot water. This will help get rid of the harmful surfactants. READ THE CONTENT CARE LABEL: On the inside of your garment, or on the hangcard, there are instructions for the care of that individual piece. On garments this will be on a side seam or back seam label. Follow those directions. On finer fabrics, use a "Gentle" cycle. Close all zippers, attach "hook and loop" closures on gloves YOU CAN USE THE DRYER, CAREFULLY: If you use a dryer be sure to use a lower / warm heat setting (Do NOT use a commercial dryer or a "Hot" setting). This will often restore the fabric and help the water and wind repellent qualities. If in doubt, hang the clothing to dry.
