1. Comes with Fleece Earmuffs: Wear our cozy beanie for ultimate comfort during cycling and outdoor adventures! Our beanie features warm, moisture-wicking, breathable fleece fabric, as well as extended oval fleece earmuffs to ensure maximum comfort and warmth. Say goodbye to cold ears and head while exercising or riding, and enhance the overall comfort of outdoor activities. 2. Practical glasses holes: On both sides of the beanie, we designed glasses holes, which are more convenient to wear cycling glasses or other professional glasses, so that the glasses are firmly fixed on our ears, not easy to slip off, and can reduce the burden on the bridge of the nose, so that we can focus more on our exercise. 3. Extra comfort and warmth under the helmet: The warm hat is too thick to wear under the helmet? Don't worry! Our helmet liner strikes a good balance between lightness and warmth, thicker at the ears, thinner at the head, and the stitching is flat, which will not add extra pressure to the head. Suitable for use under bicycle, motorcycle or ski helmets and helmets. MELASA reflective logo can be added when riding at night or working outdoors. 4. Proper amount of stretch: If you are looking for a high-performance beanie hat that fits better, won't slide off your head easily, and isn't too tight, then you can choose our hat, which is elastic and fits any size head circumference between 22.4-24.4 inches. The edges are lined with milk silk to ensure a close fit to the head and prevent the hat from sliding or curling. So you don't have to worry about the earflaps curling up like wings and stinging your ears in the cold wind.
