The Mens Fleece Neck Gaiter by HotMocs takes the essential microfleece outdoor balaclava and turns it into must-have outdoor gear. Its unmatched performance is due to our patented pocket construction, strategically placed for faster distribution of warmth. Starting at the base of the heat, the heat pack warms your core using the spine to conduct heat. The Odor-x function ensures your product will wick and remain odorless. These innovative and engineered designs are the perfect warming solution for any outdoor activity. Insert any heat pack to stay warm even under the toughest conditions. Each purchase of a HotMocs accessory includes two free heat packs for immediate use. Replacement heat packs are inexpensive and widely accessible.
