Poler Heat Bags that are air activated and come in their own resealable pouch. You can turn them on and off by simply putting them back in the pouch and sealing them. They are fantastic for use when commuting, jogging, cycling, sitting in a cold office, snowboarding and any other outdoor activity. They also keep your cell phone or camera batteries fresh by keeping them warm when its freezing out. Throw them in the bottom of your napsack if the temperature dips and you'll have toasty feet all night!
Use them as often as you like for a total of 10 hours, then keep the bag and use it for something else. They are non toxic. Properly sealed, Poler's heat bags have a shelf life of about 2 weeks once opened. Just keep in mind they take about 10-15 minutes to heat up and cool down each time you use them and reseal them. Heat bags are designed to be used in gloves or pockets, which is where they get hot. If you have one out in the open it won’t get that hot! So put them in your gloves and/or pockets!
