With winter just about here, hats and gloves are sure to make their way into holiday stockings. But if you really want to give the gift of warmth this winter, Amazon’s got a deal on a problem-solving gadget that you need to check out. The No. 1 bestselling Innopaw Hand Warmers are on sale for $36 (with the on-page coupon), down from $60 — nearly 40% off.

Some of us are not made for cold weather. In fact, some of us should get a prize for living through winter every year. We’re the ones whose hands are perpetually cold no matter what the weather. But when it’s frosty outside, our fingers turn into icicles. Are you that someone? Or perhaps you know that someone — and if you want to make their life better (or yours) these little rechargeable hand warmers will make winter so much more tolerable.

These hand warmers are small enough to fit in the palm of your hand or pocket, so they’re easy to use and carry when you’re out about. It’s a priceless product for people who spend time outside in the winter — whether it’s work or play.

“I do a lot of things outdoors,” reported one of more than 1,400 five-star fans. “I play disc golf and I deliver mail. So keeping my hands warm is crucial. This hand warmer is great. I took them to work with me and kept them on all day. Lasted six and a half hours on the low setting.”

Each hand warmer comes with a USB cable for charging. Pro tip: You can also use them as battery packs so no matter where you are, you always have a way to juice your phone.

“They double as a portable charger!!!” shared another enthusiastic shopper. “My hands are always cold at work and these are awesome at keeping them warm. I’ve only used the lowest temperature and it’s more than enough!”

They’re also magnetic, so when not in use, they stick together to make them hard to lose — and for people who need them, that’s imperative.

“These saved my Raynaud’s syndrome hands last winter,” gushed another five-star fan. “I literally used them every night when I got in bed. I would hold one, and fall asleep. Don’t know what I’d do without them. At times I’d use the high setting and run it up and down my neck for pain relief.”
