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

My favorite off brand hand warmers! These are larger than others, last longer, and provide warmth right away. Easy to use and very functional.

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.

This warmer is really good. Stay warm for many hours. A good quality product.

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.

I have ordered several boxes of the large size Iris Hand Warmers (made in Japan). I use them not just in the winter months but year round to sooth arthritic fingers. I use only one at a time and alternate it between hands as needed. The large size is easy to grip and and remains hot for 12 - 18 hours as advertised. Each warmer is individually wrapped and then sealed in a plastic bag of ten making it convenient to store a bag in a locker, glove compartment, backpack, saddlebag, etc., without having a bunch of individual warmers slipping around everywhere. The fabric covering is a little stiff compared to the Hot Hands Super Warmer but I just trim away the excess fabric around the edges to help it feel a little softer. I had difficulty purchasing Hot Hands during the pandemic so I gave Iris a try. I was sure that I would return to Hot Hands as soon as they became available. However, I'm staying with Iris because the price is reasonable and the quality has been consistent in each of the 300+ plus warmers that I have used. TIP: If I use the hand warmer for only a few hours and want to preserve it, I put it in a Ziploc freezer bag, squeeze the air out, and freeze until ready to reuse. I find this method works about 50% of the time.

Great buy. Tried one and it last and stays warm for about 12 hours. That is pretty good. Recommend for those of us with cold hands in the winter.

These take some time to warm up then get hot about 2hours in stays hot about 17 hours. Before the last hours is then turning warm to cold. They do work very good price too. Yes worth it to buy.

Worked perfectly - has the smell of metal slightly - but they worked great inside my clothes in -2F weather at Ground Hog Day.

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

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!

Some don’t even hardly warm up and the ones that do don’t last for more than 8 hours
