The adjustable, fleece behind-the-head ear muffs are the first and only ear warmers that wrap around the back of your head. The design provides superior warmth and replaces the awkward appearance and marginal effectiveness of traditional and uncomfortable earmuffs. These soft fleece ear warmers are made from high-quality, breathable fleece. Ear warmers wrap around the back of your head, so they can be worn with glasses, helmets, and hats and are not cumbersome while you work.
