THE HEAT COMPANYHandwarmers - New: 30% Less Plastic - EXTRA WARM For 12 Hours Warm Hands - 10, 16, 32 or 40 Pairs - Air Activated Heat Pads - Pocket Warmer Against Cold Hands

Extremely helpful. Went to Peak District for camping when it was -3 outside. This was the literal life saviour for cold feet and hands. Would still advise you to carry additional things like a sleeping bag, air mattress & heavy jackets as it’s not meant to be the saviour if you can’t retain heat.

Excellent for keeping the hands warm for winter golf

I bought this product to use during winter.Some of the packets weren't warm enough, a few way to warm, the rest were alright.The packets are small enough to fit under your gloves, but it will make it uncomfortable to use your hands.When activated properly, it will take a while for your cold hands not to feel cold. If you are outdoors and use these warmers, you will need gloves as your fingers will freeze.The longest they have lasted for me was between 8 to 12 hours, although the heating usually changes. The shortest time they lasted was 0 seconds as a few didn't activate.Overall, they are great to use outdoors, but not when it's freezing as it doesn't cover your all hands as the packets are small. Your fingers will freeze.

Don’t expect this product to instantly warm you, they last a long long time so bleed heat over that.They are perfect for putting in your pocket and letting the heat build, then when you want put your hand in there and it’s perfect.I just used them at euro disney, one in each pocket when the afternoon came and I had 2 little radiators all through the night.

Toasty hands and everyone is always envious that I have these on me! Good bit of kit for being outdoors for extended periods of time.

These handwarmers are amazing! They lasted well over twenty four hours,even though it says twelve! Perfect for keeping your hands warm,or anywhere else you want to put them.I can't believe how efficient they are,so easy to use, no putting them in a microwave, just tear open the plastic packaging, leave them for about ten minutes for them to heat up,although they start heating up sooner than that. Absolutely brilliant!!

We give them to the homeless and wheb we go skiingBrilliant

They just don't work! Meant to last for 12hrs but don't even get warm after the 15 minutes. Waste of money.
