People who live in the northern latitudes know how to protect themselves against the ravages of winter. They have their long thermal underwear, wool socks, sweaters, down jacket, balaclava (or similarly effective winter hat) winter boots, and gloves. This basic outfit is enough to protect most people from even the most extreme winter weather.
But if there is a weak link in this chain, it’s the gloves. For some reason, probably having to do with the intricacies of blood circulation in the extremities, gloves always seem to come up just a bit short in the warmth and comfort department. As long as there have been gloves this has been true. And as long as it’s been true, there has also been virtually nothing that could be done about it. Until recently.
In the past decade or so, the science of hand warmers has progressed to the point where today, there is really no reason why anyone should have to go through winter on the verge of frostbite. Below, we take a look at the best hand warmers on the market.
While I personally often opt for disposable hand warmers on long days, rechargeable options are excellent too. I love to place hand warmers near the core of my body so blood can better flow to my extremities, or I slide them in my ski gloves on super chilly days. Before I adjusted to winter, warmers were one of the things that kept me even remotely close to comfortable in winter months. They still provide a lot of value and make days in the snow much more comfortable. They are a valuable first aid tool too, so I keep them just about everywhere.
Editor’s Choice: HotHands Hand Warmers
- Heats up in 15-30 minutes
- Comes in several styles to warm you
- Natural, convenient to use
- Compact and very eco-friendly
HotHands hand warmers are decidedly low tech and rely on the miracle of chemical reaction to produce their hand-saving effects. Once you break the seal on a HotHands hand warmer, you set in motion a process called oxidation. Air sifts into the packet through tiny holes in the pouch and reacts with the iron inside. Iron oxide (more commonly known as rust) is then created. Salt is used to generate heat and vermiculite in the warmer then absorbs that heat and prevents it from escaping. Carbon (also in that busy little bag) is then employed to disperse the heat throughout the sack so that when you hold it, the entire bag feels warm, not just one particular area. There are no fancy-pants energy banks or LED flashlights on offer here. But these little sacks of heat may be the best hand warmers for winter. You can even put them in your winter boots to heat them before you wear them.
Being from Texas, for most of my life I was not cold hardy and relied on multi-packs of hot hands hand warmers to get me through chilly days and climbing trips. I’ll often keep one in my pocket, or if I’m climbing, my chalk bag. Additionally, I often slide one on my bra or in the waistband of leggings to keep my core warm so blood can flow to my extremities. I’m more cold-hardy these days, but I now spend much of my winters in snow, and these hand warmers keep me comfortable all winter long. I love that these stay warm for hours on end, but if you have sensitive skin and you use one of my pieces of advice above, be careful not to let the hand warmer go directly against your skin. You can usually find these disposable hand warmers at grocery stores, big box stores, sporting goods stores, and your local hardware store.

Why Trust Us
If there’s anyone that has had to learn how to cope with the cold, it’s a Texan who moved to the mountains. I went from 85˚F on Christmas day to skiing big mountains in the Cascades. I was far from ready for the cold when I first arrived and have slowly found ways to cope and increase my cold tolerance. My favorite ways to stay warm involve hot tea, hot cocoa, layers upon layers, and of course, hand warmers. On brutal days, you often need a little something extra like a pocket warmer to make it through.
Who This Is For
This guide is for anyone looking for a hand warmer. We have such a large range of options here and include additional information in the FAQ section to make sure you’re selecting the best choice for you. There’s something for outdoor enthusiasts, sports fans who need to endure a chilly game, skiers who need to ski through a stormy day, and folks with Raynaud’s.
How We Picked
When curating a selection of the best hand warmers, I opted to ensure there was a variety of heating methods from chemical reactions to a catalyst hand warmer, liquid fuel, and rechargeable options. The selection we present here offers heat for as little as 30 minutes and up to 12 hours in some cases so we serve a variety of needs. Many options also feature additional perks and features to make them more worthwhile.
How We Tested
I’ve been using hand warmers for years in a variety of scenarios, from cold climbing gyms to outdoor climbing, chilly hikes, skiing, and more. I use hand warmers on a weekly basis during winter in the Pacific Northwest, and the Cascades present a perfect chance to test the best hand warmers. Throughout the years I’ve found creative solutions like warmers tucked in a bra, to toe warmers adhered to my hip in the name of warmth. I even sometimes add them to my wrists and secure them with hair ties in a sleeve!
Features To Look For In Hand Warmers
Source of heat
Below we discuss the different heating methods used in hand warmers and their heat source.
Duration of heat
There are many ways a hand warmer generates heat and the source of the heat determines the length. Many rechargeable and electric hand warmers can offer up to eight hours of heat depending on the battery size. Disposable options can often last up to ten hours with some options with chemical reactions working for as little as two hours.
Max temperature
Many hand warmers share similar max temperatures between 115 and 130˚F. Those 15˚ can make a big difference in comfortability but it’s not quite as noticeable as you think. Any hotter than 130 could potentially burn or hurt your skin in sensitive areas so always exercise caution!
Heat settings
Electric and battery-powered hand warmers often offer multiple heat settings. There are often two to three heat settings but some boast as many as six different settings. This feature allows you to maximize the battery life and pick the perfect setting for you.
Battery life
The best rechargeable hand warmers can offer up to 10 hours of battery life, but the average and most common range is between five to seven hours.
Extra perks
Some options come with flashlights or act as power banks for your phone or other devices. Versatile products are always a win but these features can drain the battery from the primary purpose, which is to warm you and your hands.
The Many Ways To Use Hand Warmers
While everyone knows hand warmers are used to warm hands during the winter months, they can also be put to use performing an array of other important tasks, including:
Drying wet socks – If you’re in the woods and your socks have become damp, put your hand warmers inside them to help dry them quickly and effectively.
Drying wet boots – If your climbing or winter boots got damp along with your socks, put the warmers in the boots at night so that they’ll be drier for you in the morning when it’s time to hit the trail again.
Warming your sleeping bag – Sometimes we bring a bag rated to 40 degrees and it turns out to be 25 degrees. If your sleeping bag is coming up a bit short, bring a couple of hand warmers into the bag with you to compensate.
Supplying emergency body heat – If someone is on the verge of hypothermia they need to be warmed as quickly as possible. By wrapping a hand warmer in a sock and putting it in the person’s underarm you can help restore core heat and perhaps, help stave off hypothermia.
Warming massage – After a long day of trekking you can wind up with stiff, aching muscles. While you’re kicking back in the tent, break out a couple of warmers and rub them over your sore muscles to help loosen things up so you can relax.
Keeping your batteries working – Cold temperatures can be tough on batteries. If you brought your beautiful new camera into the woods with you during the winter, you may have lithium-ion battery trouble unless you can keep it warm. Put your battery or batteries in a single case with a hand warmer to keep them viable.
Relieving headaches – It’s not uncommon to suffer from headaches at the end of a long day of trekking. If your head is pounding, activate a heat pack and hold it gently to your temples to provide relief. This technique is sometimes helpful in relieving the effects of migraines as well.
Preventing frozen drinking water – If you’ve ever spent time in the outdoors during the winter, you know what it’s like to pull out your water bottle and find the contents one big ball of ice. If the mercury has dropped substantially, take a heating pad and wrap it around your water bottle to prevent it from freezing through.
Warming feet – Feet get cold too and there’s no better feeling than activating a hand warmer and using it to warm up your frozen piggies. Put one in the foot of your sleeping bag at the end of a long cold day and enjoy the warmth and comfort.
Warming food – Keeping your nice hot food warm when it’s freezing outside can be a losing battle. Unless you have some warmers with you. Instead of putting your hot food down on the frozen ground or an equally frozen picnic table, put it on a warmer or 2 and make sure it stays hot for as long as you need it to.
Hand Warmer FAQ
Q: What are the different kinds of hand warmers?
A: The following types represent the currently popular methods different warmers use to generate heat. Some of these were touched on above, some were not.
Crystallization – Chemical reactions are the ultimate in low tech and these reusable hand warmers use what are called “supersaturated solutions”. Basically, they’re a clear gel that, when properly activated, turns noticeably opaque. This opaqueness is the result of exothermic crystallization which spreads throughout the gel pack and generates heat. You then use that heat to warm your hands. You can get as much as 2 hours (or in some cases a little bit more) out of a single exothermic event and the best part is you can “recharge” the gel pack by simply reheating it in boiling water for about five minutes.
Lighter fluid – Lighter fluid-powered hand warmers like the Zippo above use petroleum naptha in concert with a platinum catalyst. The two react to create oxidation that in turn generates heat. The great thing about lighter fluid heat warmers is that they don’t need to be recharged. Just fill them back up with lighter fluid again and they’re good to go. This type of warmer was first introduced nearly a century ago.
Batteries – Battery-operated hand warmers convert electrical energy to thermal energy via a process that’s too involved to explain competently in the space we’re given here without boring you to death. These top-rated hand warmers do a great job producing heat quickly and can offer something chemical reaction warmers can’t: different heat settings. In normal conditions, they can be expected to produce heat for up to six hours. Many of these instant hand warmers can also double as power banks to recharge your mobile devices.
Charcoal – Charcoal stick hand warmers are perhaps the most “primitive” type, but that doesn’t mean they’re not effective. Their simplicity is where they shine. A typical charcoal hand warmer provides a fireproof case into which a glowing stick of charcoal is placed. As the charcoal does its slow-burn, heat is generated that you use to warm your hands. Besides their simplicity, their other big upside is that charcoal is widely available and very affordable.
Air activated – Air-activated hand warmers like the HotHands warmers reviewed above utilize the process of oxidation and a salt catalyst to generate heat. That heat is retained by vermiculite and dispersed within the hand heater pack using carbon. The duration of heat you’ll get from them can be uneven though, lasting anywhere from one to as many as nine or ten hours.
Q: Are hand warmers safe to use?
A: Yes, hand warmers are safe to use. Bu since you are interacting with heat and sometimes electricity or chemical reactions, it is important to exercise caution in general. Some folks have skin that is sensitive to heat and a protective layer should be utilized if that is you.
Q: What material is best for hand warmers?
A: There is no necessarily the best material. Your choice of warmers from the types above should be based on personal needs and preferences as they all serve certain purposes and have their best uses.
