Hand warmer patches contain natural ingredients that create an exothermic chemical reaction to generate safe, soothing warmth right when you need it. They provide up to 10 hours of continuous heat with just a simple peel and stick application.
At the heart of the hand warmer patch is a mixture of iron powder, water, vermiculite, activated carbon, and salt. When exposed to oxygen, the iron undergoes an oxidation process that produces heat. The other components help regulate and sustain the reaction.
To use a hand warmer patch, simply open the sealed packet, remove the adhesive backing, and apply it to any fabric surface like gloves, pockets, or sleeves. An adhesive warming layer will begin emitting heat right away while the core iron powder mixture kicks in to provide hours of lasting warmth.
Hand warmer patches reach up to 140°F but maintain a safe, comfortable temperature against skin. The thin construction and breathable fabric backing contour perfectly to the shape of your hands without limiting dexterity. This makes them ideal for activities like skiing, ice fishing, or football games where warmth and flexibility are both essential.
After use, the patches can be tossed in the regular trash once the warming sensation has diminished. They produce no liquid waste or harmful emissions. However, they should be kept away from children and handled carefully to avoid skin irritation when in full heating mode.
In frigid winter temperatures, instant hand warmer patches are the convenient, affordable solution for keeping extremities comfortable and avoiding dangerous cold exposure. Just stash a few packets in your pockets or bag to tackle any outdoor adventure.
