Thick Fleece Earmuffs: Make your cycling and outdoor adventures more comfortable with our comfortable cycling cap! Our cycling cap is made of warm, moisture-wicking, and breathable fleece fabric, and features extended oval fleece earmuffs for ultimate comfort and warmth. Say goodbye to cold ears and head during exercise or cycling, and enhance your outdoor activity comfort.Practical Glasses Holes: Glasses holes are located on both sides of the cycling cap, making it easy to wear cycling glasses or other professional eyewear. This ensures your glasses stay securely on your ears, preventing them from slipping, while reducing pressure on your nose bridge, allowing you to focus more on your activity.Comfortable Warmth Under Helmet: Think a thick cap is inconvenient to wear under your helmet? Don't worry! Our helmet liner strikes a good balance between lightweight and warmth, with thicker earmuffs and a thinner head area. The flat-seam design won't add extra pressure to your head. Suitable for bicycle, motorcycle, or ski helmets, as well as safety helmets. Reflective markings improve safety during nighttime riding or outdoor work.Perfect Elasticity: If you're looking for a high-performance brimless hat that fits snugly without slipping or being too tight, then this highly elastic hat is for you. It fits head circumferences of 22.4-24.4 inches (57-62 cm). The brim is lined with milk silk to ensure a snug fit, preventing it from slipping or rolling up. Therefore, you don't have to worry about the earmuffs curling up like wings and freezing your ears in the cold wind.The Perfect Gift for Outdoor Sports or Cycling Enthusiasts: This warm balaclava effectively protects your head and ears from the cold wind in cold weather, whether worn alone or under a helmet.
