HotHands Hand Warmers - Long Lasting Safe Natural Odorless Air Activated Warmers - Up to 10 Hours of Heat - 40 Pair

They are G-d sent. So useful. Small and easy to hold either in your hands or even in your pocket. In your pocket they stay hot for even longer, keeping not only your hands warm but your entire body.

These are incredible. I put them in my mittens when I’m out walking then put them in my pocket for the rest of the day. They get lovely and hot and last more than eight hours. Worked highly recommend. Will be buying more.

Best handwarmers of this type that I have found. They keep warm for at least 8 hours.

These stay warm all day, best if activated a little while before activity so they warm up. I keep mine for those days I know they will be most needed and carry them in a pocket so I can pop them into my hands as soon as I feel the need. Very pleased with them.

Not as hot as some I have tried

I get through a great deal of these, almost every night I use a pair in winter and the surrounding colder months, as I'm in the habit of a long night walk before bed every day and would otherwise get frostbite, even through thermal gloves. I put one in each glove and that's that, toasty hands for the whole journey. These last a long time, if I start them at 10pm, they're still giving off noticeable heat at 7am the next day and remain at near peak output for at least four hours from the outset - they do get very hot if confined, might be too warm for some people in some situations, but I often keep them in my chest pocket or gloves and throw them in my bed when I get home to help in the night, no bother, just a good product. Disposable, yes, but it's essentially just a material pocket filled with iron fillings, for the main, initially sealed in a thin plastic wrap - they react with air to activate, the plastic wrapper is non-negotiable.

Have been using these hand warmers for the last 4 winters for daily dog walks. I have them in my gloves for the walk then put them in the pockets of my “lounging pants” for the rest of the day. No need to have the heating on, they stay toasty warm for about 12 hours. Wouldn’t be without then now.

Easy to use and lasts all day, good value
