Hot and windproof - all headphones were built with a fleece inner primer of the ear heater without bandites. Between the Polar Primer and the outer shell, there are twice the Thinsulat to help prevent the wind from overheating. Unlike the majority of ear heaters with a winding around the design, there are no headphones. Our stylish design provides warmth without sacrificing your appearance. For those who have longer hair headphones, it is hard to realize that you have even found them for those who are well stuck behind your hair. Each package comes with a hotter warmer drawn on each ear. This compact design provides easy storage and transport. Most customers order several pairs and leave a series of ear bags to always be ready in each jacket. Store in a closed position to protect the appropriate session. Some popular activities where customers use their ear bags but are not limited to them: Running, skiing, cycling, ice skating, snowboard, etc. Sizing is important to ensure that the headphones sit comfortably and stay ly. 80% of adults fit medium and large dimensions. Most children have a small need. Please follow the dimensioning graph and take a correct sizing of your ear: Small: 2 inches, middle: 2 inches -2.75 inches, large: 2,75 inches. We do not recommend wearing them with larger earrings, such as large circles.
