The M.T.N. (Micro Tech Neckwarmer) Neckwarmer from Coal Headwear incorporates moisture-wicking polyester to provide your neck with protection and warmth. The polyester will block water, sleet, snow and sweat from getting the M.T.N. soggy and uncomfortable for those days on the mountain. The neck warmer is finished with a contrast embroidered logo. Based out of Portland, Oregon, Coal Headwear has been committed to making hats, scarves, and other items more than just accessories since 2002.
