HotHands Toe Warmers Features The HotHands Toe Warmers use an air activated heating element meaning the warmer begins producing heat as soon as it is exposed to oxygen with no batteries charging or preparation needed. Each warmer is built ultra thin allowing it to sit comfortably inside a boot without creating pressure points or shifting the fit of footwear during long days outdoors. An adhesive backing holds the warmer securely in place on the bottom of a sock preventing it from bunching up or sliding out of position during activity. Odor absorbing activated charcoal is built into the warmer helping control foot odor during extended wear in the field. Each warmer is rated for up to 8 hours of heat enough to cover a full day of hunting ice fishing or outdoor work in cold conditions. This package includes 40 pairs giving outdoorsmen enough supply to get through an entire cold weather season without needing to restock. A 4 year shelf life means the warmers can be stored well in advance of the season and still perform reliably when needed. HotHands Toe Warmers are TSA approved for travel and are available for sale at GrabAGun for hunters and anyone spending long hours outdoors in cold weather.
