THE HEAT COMPANY Handwarmers - 10 or 40 Pairs - NEW FORMULA - Official Supplier: Austria Ski Team, Snowboard Germany and Swiss Ski - EXTRA WARM For 12 Hours Warm Hands - Air Activated Heat Pads

I bought these to promote blood-flow following post-hand operation as there is vascular damage where the fingers keep going ice-cold. I read reviews on similar products but went with these on the apparent testimonial of supply to cold-weather sport teams. I risked the purchase of the larger pack as a possible money saver and I am not disappointed.Remove from packaging-leave exposed to air for about 15 minutes then slip inside a glove. ( I use 'toasters' which are specifically designed for cold weather and these heat pads fit inside the zipped pocket of the glove).Honesty, the glove has been relatively hot up to around the 10 hour mark and still remained warm between the 10-12 hour points. This has been the case for the last 6 days.I certainly recommend this product and would purchase again from this supplier who delivered as promised.

Very useful especially if you have Reynauds, or are doing the Big Sleep Out in December! They take about 30mins to get up to temperature, so get them out and give them a shake a while before you go out. They last for hours, so it's not like they're going to run out before you get home! Handy to have a pack tucked in your bag

These little bags of wonder are amazing! I always have cold hands, no matter what I'm doing and after carrying these around I had warm hands for the first time in about 2 years! Can't recommend them enough! And they really do work again if used for a few hours, then resealed in an air tight bag and left to cool, just expose to air and shake them about again and voila! Warm hands! Fantastic product, wish I'd bought them sooner!

Hi I ordered these hand warmers as a last minute extra stocking filler. Arrived early Xmas Eve instead even though expected date was 28th Dec so I was really pleased.My daughter hasn't used them yet but I'm sure they'll be great

Wow these heat pads are great. My hands are toastie no matter how cold it gets. I have a mobility scooter and these are great for putting inside my gloves and if it's that cold put a pair in my shoes

I’ve used a different brand’s heating pads before and I have to say these stay remarkably more hot than those. As someone who gets very cold these have been excellent in keeping me warm during this never ending Winter we are having.

Took these with me to stay warm at 3-4000m. Up there they didn't really seem to get warm at all. I'm not sure whether it's because it was too cold for them to make any real difference, or because the air was too thin for them to have any oxygen to react with. When I came back down I tested them again and here they clearly do get warm, so they do technically work, they just didn't help me.

These work exactly as they should do and stay warm for up to 12 hours. I would definitely recommend
