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. Pearl Izumi's latest warmers feature a new, softer Thermal fleece fabric with improved stretch, which makes both fit and comfort exceptional. But the 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.

"The PEARL iZUMi Elite Thermal knee warmers have quickly risen to the top of my gear bin for any day that looks even a little chilly. With a mid-width silicone-lined band, I can position them on the least-squishy part of my leg for minimum sausage effect and trust that they'll stay put. Their water-resistant treatment will bead light precipitation, and the fleecy, breathable liner makes for a cozy feel that doesn't get clammy." — Lydia Tanner, Bicycling Magazine.
