2021 Upgraded Design with Glasses Hole Get yourself ready for winter with our thermal helmet liner with glasses slots! Our winter skull cap, with smooth wind-resistant surface and lined with cozy fleece, which adds to the warmth as well as comfort and retains heat effectively, helps keep the wind chill out and keep your head warm while running or cycling in chilly weathers. The warmish EAR FLAPS are designed to fully cover your ears and provide an excellent barrier from the cold. ALSO PERFECT AS HELMET LINER: We have slightly enlarged the size of this cycling cap and used extra stretchy fabric in order to accommodate most head sizes. Our beanie hat in elastic full-coverage design fits head circumferences from 20" to 24" snugly and is yet not so tight as to be uncomfortable. Thanks to its non-bulky design, our head cap serves also as a helmet liner and fits comfortably under various kinds of helmets. A simple UPGRADE which provides much more convenience We have added practical glasses holes on both sides of the cycling hat, allowing you to wear eyeglasses comfortably without having your glasses continuously pressing into your temples. The glasses slots feature a reflective sign to keep you visible to oncoming traffic also in dark circumstances. Ensure yourself a compact skull cap which meets your various needs! Our motorcycle head wraps, warm yet lightweight, fold down extremely small and fit even in your pocket. Take this small beanie with you and get yourself ready for outdoor activities such as cycling, motorcycling, skiing, running or hiking.
