It’s 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.
