Chemical warmers are inside specially designed air-tight packages which keep the warmer fresh and ready for use. When opened, air comes into contact with a breathable warmer. The exposure to air activates the natural ingredients inside the pouch, causing the warmer to heat up. The special pouch material controls the air exposure to the contents inside the warmer, allowing it to provide long-lasting heat.

Air heated warmers or chemical warmers are convenient, relatively inexpensive, safe, natural, and very easy to use. You can place them in your hands or pocket for hours of warmth, or use specially designed products with factory-made pockets just for chemical warmers.
