Ergodyne Body warmer pads N-Ferno 6997, 7.6 x 12.7 cm, self-adhesive

The N-Ferno 6997 Adhesive Body Warmers stick directly to clothing and provide up to 12 hours of warmth where you need it most. With their self-adhesive backing, these air-activated heat pads attach easily and securely to the base layer or inside of jackets, gloves, hand warmers and more. They are designed for larger areas such as the chest or
back.

To activate, simply open the package. The natural ingredients begin to heat up when they come in contact with oxygen - no batteries required. You can also shake the pack to speed up the heating process.

Heat packs should never be placed directly on the skin. These self-adhesive body warmers are not reusable and should be
discarded once the warming effect has worn off.
