The Heat Company Handwarmer XL

When even the warmest mittens don’t keep your hands from freezing, it’s good to have a pair of hand warmers with you or a single big one. Slip this inside your glove or pocket; it’ll keep your hands warm and functioning for hours. It’s also comfortable on more leisurely outings and other winter shenanigans.

You can go far even in extreme cold with suitable gloves and equipment. However, sometimes things go sideways, and temperatures drop so low that it’s not just about comfort anymore—but survival. Carrying a source of heat that’s easy and quick to use on any winter trip is wise. If something goes wrong and your hands start to freeze, this might save you from frostbite or worse.

Use

The hand warmer is sealed in an airtight pouch. Open the pouch and pull out the pad, which will activate once it comes into contact with air. It should take a few minutes to warm up, but you can speed the process up by putting it in your pocket. Don’t cut or pierce it. Bring the used hand warmer with you after you’re done and dispose of it in urban waste. Don’t be a fool by leaving them in nature.

If you don’t need to use it for the whole time, you can put it in an airtight bag and resume use later. The warmer will re-activate once you take it out again.

If the pad starts to burn you, discontinue use.
