IRIS USA Hand Warmers, Regular/Large/Jumbo, 30/60 Individual Warmers, Regular/Adhesive Body Warmers Up to 10/12/18 Hours Disposable Handwarmer Bulk for Hot Hands Feet Chest Back, TSA-Approved, Camping

They work really well and stay warm long. Definitely ruined. Recommend these hand warmers.

These hand warmers work really well. They heat up quickly and keep my hands warm for a long time. I even put them in my bed on cold days, which makes it extra cozy. They’re small and easy to carry, perfect for winter. Very useful—would recommend!

I got these during a prime sale in Sept while they were 1/2 off. And, I am soooo happy that I did. These things are huge. When they say that they last for 18 hours that is exactly what they do. And, they can get extremely hot, be careful about who you allow to have them and where they will be used. An overlay would be good for the very yound and the very old for sure. The trick is to always keep them covered whether in your pocket, a sock, under the covers, etc. because if they are exposed to too much air they will cool off. If they do cool off w/I 12 hrs of opening, just shake them vigorously and place them back in your pocket and they should reheat. They are good for camping, hiking, sitting out by the fire on a cool night, off grid life, and to give away to the homeless in cold weather. I will be purchasing many more of these.

Absolutely awesome product. They stay warm a really long time. I have Reynauds Syndrome and cold hands mean pain. This is great for meetings where they keep the air way up.

work well

Great product and even better customer service! The box had been opened, but the seller included a bonus stack of warmers that made my day. These stay hot for well over 12 hours—far exceeding my expectations for the price. I haven't clocked the exact max temp or the full 18 hours, but for keeping me warm on cold days, they’re perfect. Take my money! A++

This is a delayed review. I have used these for over a year and they work well, last a decent time and have withstood abuse in the back of a pack, truck and pockets. These are not only cold weather heaters. They are good for first aid, sore backs and shoulders, etc. I will buy more when they run out.

I bought these as they were a larger size, but compared to other brands, these don't get hot, more like mildly warm. They are kinda a hassle to warm them up, you open and shake but they get barely warm. You have to keep it in your pocket to feel any warmth. Don't waste your money like I did.

Amazing! Very large and stay hot for a long, long time! Great for all day outdoor adventures!

I bought these for emergency heat after a week long blackout that happened in March caused by a massive ice storm. I keep some in the house and some in the car. We havent had another emergency yet but I have also been using them to relieve menstrual cramps and joint pain

Warms up within a couple of min & stays warm in your pocket as described. Good choice!

Works like a charm, keep my belly warm all day

This was a great deal. When you Have kids doing out door activities like parades, you can stuff these all over them and no more complaints!
