THE HEAT COMPANY Handwarmers - 10, 20 or 40 Pairs - EXTRA WARM - Hand Heat Pads - 12 Hours Warm Hands - Instant Heat - Air Activated - Purely Natural

These hand warmers are perfect. I open and shake them and put one in each glove. The heat lasts for hours. Wonderful.

Used when camping in approx 0 to 3'C. Put 2 in my sleeping bag before bed, giving them 5 mins beforehand to warm up. Woke in the night with them burning my legs. They definitely get warm, just place them somewhere sensible. Would purchase again.

They stay warm for a long time and are great to use when watching or participating in outdoor sport. They lost a star because of their small size.

Really impressed with these. Last 24 hours. I had them for NYC in Dec. Would recommend.

I have circulation problems. My feet and hands are always cold. I recommend this product. The hand ones are worth using, but the foot ones are also worth buying. I only recommend this product from this company; it meets my expectations.

Used for a ski trip, the temp was -15 on the day and they kept the hands nice and warm Would recommend Follow instruction

Not heating up enough for pain relief. Have given them away.

Pretty good, not sure if I used correctly as it would seem to go cool but then heat back up. Did seem to have some warmth left at the end of a 12 hour shift. Overall good for what I wanted.
