The HotSnapZ are a fast-acting hand warmer is perfect for people looking for an inexpensive and quick pick-me-up rather than an all-day hand warmer. Unlike traditional hand warmers, this one uses sodium acetate (basically baking soda and vinegar), which has an unusually high freezing point. When the metal disk is tweaked, it sends tiny metal particles into the sodium acetate solutions, which starts a chain reaction that releases all the heat in the solution as the crystals themselves freeze. This hand warmer style is so straightforward that you can make a DIY version.
Something else great about the HotSnapz co*pared to the traditional style in our best overall pick is that they can be reused many times by simply placing the packet in boiling water for 10 minutes and then allowing it to cool to room temperature.
If you don’t use hand warmers consistently—perhaps you just want a pair to stash into one of the best hiking backpacks—then a battery-powered or lighter-fuel option may be more investment than you are looking for.
But single-use hand warmers that you toss in the trash at the end of the day aren’t environmentally sustainable.
While at first glance the Ignik Hand Warmer looked like the other disposable single-use hand warmers in my test, its contents can be co*posted, either in your home co*posting bin or your city’s co*posting program. Four of the ingredients in the hand warmer—vermiculite, activated carbon, cellulose, and salt—will break down anywhere between a couple of weeks and a couple of months depending on your home co*posting setup, while the fifth ingredient, iron shavings, provide essential minerals to the soil.
The Ignik’s 108-degree max temp was the lowest of the best hand warmers. But It should be noted that, for testing, I randomly picked one of the hand warmers out of the packet and measured its temperature. That hand warmer turned out to be significantly less warm than the other hand warmers in the packet.
co*pared to the Zippo and two sodium acetate hand warmers, the Ocoopa was impressively easy to use, making it the best multiple-use hand warmer in my test. Upon opening the box, I plugged in the hand warmer using the supplied cable. Once all three lights next to the power button were a steady blue, I unplugged it and turned it on. It immediately started warming up; in fact, this was the fastest warming product I tried. Pressing the power button two more times set the hand warmer to high, which was what was used during testing—users can expect this hand warmer to last longer when set to a lower temperature setting. While this hand warmer is pricier than others I looked at, its simplicity and high performance make it one of the better values.
If all you care about is the hottest hand warmer—and I mean really hot—then the Zippo 12-Hour Refillable Hand Warmer is the right choice for you. Just don’t toss the small tote, which co*es with this hand warmer, in the garbage: you’ll need it to keep it from burning your skin.
While the Zippo Hand Warmer emits an impressive amount of heat, I found it fairly co*plicated to use during testing, especially co*pared to the simplicity of the Ocoopa. First off, this hand warmer can’t be used straight out of the box—you need to first acquire lighter fuel, which is sold separately. The instructions for the Zippo warn you not to spil* any of the lighter fluid while filling the tiny plastic filling cup, which sort of resembles a watering can, and then tipping the lighter fluid into the hand warmer itself. I was unsuccesful in that and spil*ed lighter fuel both times. The instructions then further state the hand warmer should be allowed to stand upright for at least two minutes prior to use, and that it is important that the warmer not lay flat before being ignited; however, the design of this hand warmer is not conducive to standing upright.
The Zippo Hand Warmer was tested straight out of the box without the provided pouch to assess maximum temperature. That initial round of testing demonstrated that users need to be exceptionally careful with this hand warmer, as the temperature of the metal could easily result in a contact burn on someone’s skin. The second round of testing, using the attached pouch, showed that users can safely use this hand warmer, assuming they are careful. That being said, this hand warmer is not an appropriate choice for children due to the amount of heat it generates.
It’s worth noting that the instructions for the hand warmer state that the hand warmer may not operate for as long as it can during its first use, which was what I measured during the initial testing.
There’s a reason beavers survive in some of the planet’s coldest places. There’s also a reason why beaver fur has been used by Indigenous people to stay warm for millennia. It works. Aurora Heat formed in 2015 by a Canadian daughter of trappers who recognized the warmth generated by dressing in furs. The hand and feet warmers she created reflect that knowledge.
The Aurora Heat hand warmers trap heat generated by your body and keep it there, which means they take longer than a chemical or electric warmer to reach temperature. But unlike other warmers, they never run out and are incredibly soft. They’re also best used before your hands are already cold. Place them on top or underneath your fingers. For maximum warmth (though prepare for your hands to sweat if you’re moving or it’s not cold enough outside), consider buying two pairs to place warmers above and below your fingers. —Christine Peterson
We realize heated glove liners are not exactly hand warmers, but they function in much the same way. These liners are a perfect way to keep your fingers warm with plenty of dexterity if temperatures aren’t too cold, and also keep them warm inside of mittens when temperatures drop really low. Consider them hand warmers from the tips of your fingers to your wrists.
Our tester wore these through last year’s frigid Wyoming winter, where temperatures dropped consistently below zero. He wore them primarily while pushing the snowblower to clear snow from his large driveway, noted that even his fingers, which are particularly sensitive after a woodworking accident, remained warm and co*fortable.
On their own, they offer some heat but won’t be as warm as bulkier heated gloves. They’re perfect used inside of mittens. —C.P.
Your Clothing
Hand warmers can be great after ungloving your hands for some fine motor work, but they are no substitute for appropriate clothing. If you find that you are regularly cold in the backcountry, consider upgrading your outdoor wardrobe, such as with a pair of the best hiking socks.
Mechanism
While most single-use hand warmers use iron powder to produce heat when exposed to the outside air, reusable hand warmers employ a number of mechanisms, including sodium acetate, lighter fluid, and internal batteries. The advantage of the single-use warmers is that they are the simplest to use: once the package is opened, they start warming up instantly. Reusable hand warmers require some foresight to ensure they are juiced up before you head outside and, in the case of those that use lighter fluid, an extra level of care.
Duration
The length of time that the hand warmers in my test provided heat for varied considerably. When choosing a hand warmer, consider how long you expect to be out of doors for, and whether your hand warmer will serve as a pick-me-up or an all-day source of heat.
Maximum Temperature
A couple of the hand warmers in my test (the Zippo and the Ocoopa) are capable of reaching temperatures that would not only be unco*fortable to touch but could also cause burns if left exposed to the skin for too long. The Zippo’s 180 degrees and Ocoopa’s 135 degrees can cause second-degree burns in seconds, but both came with cloth sacks meant to prevent direct contact with the user’s skin.
Suppose you are planning an outdoor trek in an exceptionally cold environment. In that case, those high heats may be exactly what you need, but many individuals may find these temperatures to be excessive for typical outdoor activities.
While single-use hand warmers can cost as little as a dollar (if bought in bulk), electric hand warmers can run up to $30.
Single-use hand warmers that use iron powder can last up to eleven hours, while sodium acetate hand warmers typically only last an hour or two.
The maximum temperatures of the hand warmers I tested varied considerably, from a so-so high of 108 degrees up to a scorching 189 degrees.
Since 1898, OL has been a leading authority in testing and reviewing hunting gear, fishing tackle, guns and shooting equipment, and much more. We have more than a century-long history of evaluating products, and we’re now bringing that expertise to online reviews. Our editors are experienced outdoorsmen and women, and most importantly, we’re trained journalists. We prioritize field testing and objective data when reviewing products. We conduct interviews with gear manufacturers and engineers as well as outdoor experts so that our readers have an understanding of how and why a product works—or doesn’t.
Advertising does not influence our gear reviews and it never will. While we always focus our coverage on standout products—because we want our readers to be aware of the latest and greatest gear—we also cover the flaws and quirks of any given product.
During testing, I found the Grabbers to provide the most impressive heat among the traditional, budget-style hand warmers, while the Ocoopa was an excellent reusable option for those willing to spend a bit more (and who aren’t watching the weight of their gear). Remember: while the best hand warmers can help take the edge of a frosty morning, they are no substitute for appropriate clothing, such as the best puffer jackets.
