Heat Factory Large Size Hand and Body Warmer - 20+ Hours Heat Each (30 Warmers)

Heat Factory's large size warmers can be used in pockets, stadium cushions, sleeping bags and many other Heat Factory accessories. Each warmer provides 20+ hours of reliable, even heat. Warmers are safe to use, odorless and non-toxic. The Heat Factory warmer is a soft, lightweight pouch containing a biodegradable mixture of iron powder, charcoal, salt, sawdust and vermiculite. When exposed to the air, an oxidation process takes place that generates heat. Heat Factory warmers are specially engineered to provide heat that is long-lasting, comfortable, and even. Heat Factory continually tests its products to ensure that you receive only the highest quality warmers that will consistently deliver warmth as advertised. Once activated, Heat Factory warmers can even be saved for later use (preferably within a week) if placed in an airtight container. Unopened, the Heat Factory warmer has a shelf life of three years or more.

Stay warm even when the mercury dips with these Heat Factory large hand and body warmers. Each warmer--the box comes with 30 total--is designed to generate heat for up to 20-plus hours, making them ideal for snowshoeing, altitude camping, or just hanging out on a cold winter day. Not intended for use in open air, the warmers' soft, lightweight pouches contain an inert mixture of iron powder, charcoal, salt, water, and vermiculate. Once exposed to air, the warmers will experience a natural exothermic reaction, helping them generate consistent and prolonged heat. It's like having your own personal heating pad inside your pocket or coat.

Made of soft cloth lined with a very thin layer of porous plastic, the warmers are easy to use. Just open the package and expose them to air. The warmers are versatile enough for almost any situation: they'll slip into pockets, stadium cushions, sleeping bags, and almost anything else. And should you open a warmer and decide you don't need it, you can save it for later use (preferably within a week) if placed in an airtight container. Unopened, the Heat Factory warmers have a shelf life of three years or more. Odorless and nontoxic, each warmer measures 5.5 by 4 inches.
