Supplies and Accessories
Keep hands warm during cold winter days with Ergodyne N-Ferno hand warming packs.
Stay warm and comfortable no matter how cold it is with Ergodyne N-Ferno hand warming packs. These self-contained sachets are filled with natural ingredients that become toasty as soon as they're exposed to air. Opening a pack activates the pad, and each hand warming pack can keep emitting warmth for up to 12 hours. If you're only in the cold for a little while, store the partially used Ergodyne N-Ferno hand warming pack in an air-tight container, ready to use again.
