These flexible knee warmers are perfect for when theres an extra gust in the wind. Made with an Ergonomic TourTek Zero X2 windproof panel, these warmers have an extra panel over the knee and upper leg to ensure youre warm enough for the climb. The flat seam construction has minimal bulk to ensure the fabric doesnt limit your mobility. For good measure, weve utilized our BodE Thermal Heat fleece-lined stretch knit panels to wick away moisture and add another warm layer. Weve also added our soft gripper elastic at the top openings so that you dont have to worry about your knee warmer slipping down during the ride. And in case youre planning to extend your ride into the evening, reflective logos are in place so that no one misses you on the road.
