These flexible knee warmers are perfect for when there's 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 you're warm enough for the climb. The flat seam construction has minimal bulk to ensure the fabric doesn't limit your mobility. For good measure, we've utilized our BodE Thermal Heat fleece-lined stretch knit panels to wick away moisture and add another warm layer. We've also added our soft gripper elastic at the top openings so that you don't have to worry about your knee warmer slipping down during the ride. And in case you're planning to extend your ride into the evening, reflective logos are in place so that no one misses you on the road.
