Product Details
The N-Ferno 6997 adhesive body warmers are designed to adhere directly to clothing for up to 12 hours of warmth where needed most, measuring 3 in x 5 in (7.6 cm x 12.7 cm). These air-activated heat pads feature an adhesive back that allows for easy and secure application to base layers or the interiors of jackets, gloves, and hand warmer muffs, though they should not be applied directly to the skin. Each box contains 40 individually sealed warmers made from iron ore, which activate instantly upon exposure to oxygen, eliminating the need for batteries. Warming packs help regulate core body temperatures in cold conditions and should be disposed of after their warming effectiveness has worn off, which can last up to 12 hours. These body warmers are particularly suitable for individuals working in construction, transportation, warehousing, and refrigerated areas, as well as for outdoor weekend activities like hunting, climbing, running, cycling, and skating.
