Criteria Used for Evaluation
Overall Fit
It is important to remember that if the item you’re using isn’t comfortable to wear, chances are you won’t use it.
How many pairs of winter shoes do you have sitting in your closet because they cause blisters?
For this reason, among others, the overall fit and comfort of an item are important as well. Thankfully, with a few minor exceptions, such as being bulky or not fitting well for certain types of individuals, all items on our list feature the ability to be worn or used by a wide range of individuals.
Because this guide features many cold weather gear options, for those products such as a blanket or extremely cold weather boots, we considered this category as the size. Even if the product is only offered in one size, we discussed the dimensions and how well this size would serve you, as well as how small they can be packed up.
Comfort
You will want to know if reviewers think the material is itchy or abnormally fluffy and soft.
As mentioned above, the comfort of an item is one of the most important factors to pay attention to before purchasing.
Each item on this list is important to keep you warm in the winter months. With some of the clothing items on our list, we found that they felt a bit stiff before being worn in and washed. We also took into consideration that you will be wearing these clothes all day and discussed how comfortable they would be for hours at a time.
As for the blankets and sleeping bags, we discussed the comfort of the products, as well as the temperature ratings that the products are recommended for.
Weather Resistance
The first thing that you need to worry about when buying gear for cold weather is whether or not it will protect you in such an extreme environment.
Things such as frostbite, hypothermia, dehydration, and injury are all acerbated by colder temperatures, and having something that can help protect you in that type of situation isn’t just a good idea; It’s a vital one.
We discussed the insulation of each product and how well they protect against rain and snow. T
Materials
Of course, comfort, protection, and weather resistance are often dependent not only on how an item is made but also on the materials used to make it.
There are quite a few materials that are standard in this type of clothing, including insulation, rip-stop nylon material, waterproof or water-resistant fabric, rubber, and natural fibers designed for winter apparel.
While not every item here had every material we would have liked or expected, they all have a good combination of the materials you need to get the job done. Along with the materials that an item is made from comes durability. If the product is stitched well and made from quality fabrics, chances are that it will last longer.
Durability
The items on our list are designed to be long-lasting and tough.
Whether it’s through the use of reinforced seams, rip-stop material, layering of panels and fabric, or simply using metal zippers for added strength, everything here is designed to help you get the job done. Considering that many of these items will only be worn for a few months out of the year, it is important to know that they will not deteriorate in storage, or fail you mid-way through the season.
For many of these items, you can learn a lot about the durability of the materials used. Each product is different, but you should always pay close attention to the stitching, weather resistance, and overall strength of the product.
Another great way to learn more about the durability of a product is to see what the reviewers have to say. They have tried and tested the item and aren't afraid of telling the truth.

It comes with its own stuff and storage sack to help compress the down and help with packing inside your pack.
Comfort
The goose down fill gives this sleeping bag a soft feel that is durable enough to prevent the down from poking the inside of the bag.

Weather Resistance
Based on the materials used, this sleeping bag can easily keep you warm and dry down to a temperature of -40 degrees. Not only does it feature an easy to use side zipper that helps to keep out the cold, but also a mummy-style hood to help you keep your ears, face and neck protected.

Durability
The rip-stop outer shell and double seams make for a fairly durable sleeping bag that can withstand almost everything that you may encounter on a winter camping trip.

4. Ergodyne N-Ferno 6823 Balaclava
When it comes to cold weather gear, especially when the temperatures drop significantly, protecting your face from the onslaught of the bitter cold is extremely important. One of the best ways to accomplish this goal is through the use of a balaclava.
Read moreOverall Fit
This balaclava is well suited to be worn by both men and women, and can easily fit just about any size adult head. The fleece material is easily stretched over the head of even larger heads, and easily adds warmth and comfort for those with smaller than average heads as well.
Comfort
For the most part, people found this balaclava very easy to wear, and comfortable even under hoods, other hats, or goggles. There were some issues with glasses fogging up if both the nose and neck area were covered, but most people found this problem disappeared with practice.
Weather Resistance
This balaclava easily protects your face from the biting winter wind through a series of wind-protectant fabric panels around the nose, mouth and neck area. In addition, the head covering is fashioned from a thicker fleece material that is also lightweight and easy to wear overall. Some found the top portion that covers the head to be a bit thin, and it is recommended that this balaclava is used in conjunction with other head coverings.
Materials
The material used to create this particular balaclava is a combination of fleece and a stiffer fabric used in specific areas to aid in the protection from the wind.
Durability
Overall most people found this to be a bit on the less than durable side when it comes to the construction and thickness of the material. There were also cases of some of the balaclava tearing slightly at the seams.
Summary
If you’re looking for a great way to protect your head, face and neck from the bitter cold, a balaclava like this one is a surefire necessity. This particular one stands easily out from the west based on its hinged face mask area and windproof paneling that provides both versatility and protection overall.
5. Swiss Safe Mylar Blankets
When the temperature starts to drop, and you don’t have all your cold-weather gear in tow, having these Mylar blankets can literally save your life. Designed to keep heat close to you where you need it most, these lifesavers can be carried on your person in just about any situation imaginable.
Read moreOverall Fit
When fully deployed, each of these Mylar emergency blankets measures approximately 52 inches by 82 inches and weighs a mere two ounces. They are a great size for wrapping yourself in the reflective warmth or to create an emergency shelter for you or another person if necessary. Unlike many emergency blankets that are hard to fold and store away, these blankets from Swiss Safe offer an easy to fold version of a relatively large blanket. They fold down into a compact shape that can easily fit into your backpack, hip purse, or even your coat pocket for easy retrieval.
Comfort
Most people who purchase these blankets keep them as an emergency blanket. For those who have used them, they say that they are comfortable to use and extremely warm. One of the nice things about this particular entry on our list of the best extreme cold-weather gear is the sheer number of different ways that it can be used. In addition to providing emergency protection from the cold, it can also be easily used as a tent footprint, as a rain poncho, or even as backpack cover during inclement weather.
Weather Resistance
In addition to providing a verified way to conserve body heat, these Mylar emergency blankets are also wind and waterproof, making them an ideal choice when you need to protect you, or your belongings from the elements.
Materials
These blankets are made from a type of polyester material called mylar. While some found these emergency blankets thinner and slightly smaller than expected, most found them to be quite useful and durable in most extreme weather situations.
Durability
The only substantial complaint that we found was that the Mylar material sometimes weakened along the fold lines due to excessive bending and creasing.
Summary
If there is one item that you truly should have in your arsenal of cold-weather gear, a quality emergency blanket is it. While we certainly would have liked to see more durability and a slightly larger size in the case of this example, it’s still a great Mylar blanket for the cost.
6. Kamik Greenbay Boot
When it comes to trudging through the snow and ice, having the right pair of cold weather boots is essential. One of our favorites is the Kamik Greenbay 4 boot. Designed to perform in frigid temperatures, these boots are known for keeping the cold snow and ice at bay when you need it the most.
Read moreOverall Fit
About three-quarters of the people who bought these boots found them to be true to size and comfortable. It should be noted that just under a quarter found them to slightly larger or smaller than expected. Additionally, quite a few women bought these boots and found them to be more comfortable than female extreme weather snow boots.
Comfort
Overall, most people found these boots to be comfortable to wear, but a few did complain that there wasn’t quite enough padding in the calf area, and the boots needed to have better adjustability to account for layering during colder weather.
Weather Resistance
One of the best reasons to get these extreme cold weather boots is their superior protection from the bitter temperatures of extremely cold weather. In addition to keeping both your feet, ankles and lower calves relatively warm, this boot also features great protection from water, ice, and snow.

A good pair of coveralls ensures that your precious body heat has no means of escaping. It may come in at a steep price point, but it’s a perfect option for those that want to stay active and warm this winter.
Read moreOverall Fit
Classic winter gear often has the reputation of being big and bulky, which severely hinders your full range of motion. If you need to stay limber and active while engaging in outdoor activities this winter, a good coverall is a great option.
Comfort
We also like that the quilted polyester lining of this design helps hold in body heat to keep you warm all day long. It also boasts a myriad of pockets to store extra gear, and interior pockets as well to keep your phone warm and dry in extreme temperatures.
Weather Resistance
What makes these coveralls stand out from the back is found in the construction of the exterior shell. To stay warm, you need to stay dry. The exterior shell is composed of 1,000-denier Cordura nylon and is treated with a water-repellent substance to keep you high and dry.
Materials

Summary
This design from Carhartt is a little more expensive than some of the others out there, but we feel that it is worth every penny.
8. Ozero Winter Gloves
While there are lots of great choices for winter gloves out there, one of the best we’ve found is Ozero Winter Gloves.
Read moreOverall Fit
Most people found these gloves to be well-fitting, if slightly large for smaller hands. If you are someone who has smaller than normal hands, you’ll probably want to order a size smaller than you usually do. One of the great features of these gloves is the ability to easily move the fingers independently while still keeping them quite warm indeed. There were very few complaints about being able to grasp small items, fasten or unfasten buttons or snaps, or even use handheld electronic items. It should be noted, however, that these gloves are not designed for touch-screen use.
Comfort
The combination of leather and polar fleece material makes for a very comfortable and flexible glove overall. While the sizing may be uncomfortable for some, most find that in time the stretch of the leather and the softness of the fleece is a good combination.
Weather Resistance
While these gloves are not waterproof, they certainly do provide great protection against the cold temperatures and wind. They are rated to offer protection down to -40 degrees, but most people found that they were good down to the - 20-degree range, which is more than adequate for most situations.
Materials
These gloves are fashioned out of a combination of deerskin leather, polar fleece, and cotton lining. They are very flexible, warm, and provide great protection from wind and colder temperatures.
Durability
If worn casually and gently, you can expect great durability from these gloves. However, as mentioned, they are not waterproof which may be a deal-breaker for some.
Summary
While we would have liked to see these gloves as being truly waterproof, no one can deny that they are a great pair of gloves if you need to keep your hands and fingers warm while using them. If you’re looking for a great glove that offers great dexterity and warmth, these are a great choice overall.

To hold in the heat on cold days, a good base layer is ideal to stay nice and warm.
Read moreOverall Fit
This design comes in a wide variety of bright color options in addition to basic black. It is also offered in five different sizing options to ensure that you get the right fit for your body type. According to previous users, this design fits just as expected when using the provided sizing chart.
Comfort
What we love most about these pants from Smartwool is that they fit tightly, which makes them incredibly effective as well as easy to layer under coveralls or snow pants. They may cost a bit more than other designs out there, but we feel that they are well worth it.

What makes this base layer unique is that it is composed of 100 percent Merino wool. Merino wool is perfect for cold climates because it has all of the heat-retaining properties of classic wool without the itch and extra weight.
Durability

The great thing about a base layer is that it can be layered under snow pants when the temperatures really plunge, or you can wear them alone in the warmer months.
12. Terramar Thermasilk Liners
Even if you have wonderful gloves, having the option to put a liner underneath them is a great way to add an extra layer where you need it the most. One of our favorite liner gloves by far is the Terramar Thermasilk Glove.
Read moreOverall Fit
The majority of people found these gloves to be snug, but comfortable, with only a small fraction, about 15% indicating that the size was either slightly smaller or slightly larger than they desired. The sizes range from extra-small, which would fit an adult hand size six to an extra-large, or a size 10. Overall, these glove liners provide for great manual dexterity, and if worn on their own (which we really wouldn’t suggest during colder temperatures) they offer about as much flexibility and dexterity as you would see without gloves.
Comfort
Most people found this option to be fairly comfortable. Provided that the correct size is purchased, they do allow for some stretching overall, but not as much as other liner gloves.
Weather Resistance
These are finished with a ClimaSense treatment to adapt to your body’s temperature and keep you comfortable. While these are not waterproof, they are meant to be worn under another pair of gloves, so that shouldn’t be an issue.
Materials
These gloves are fashioned out of 100% silk material which is great at retaining heat and pulling moisture away as needed. While it doesn’t stretch as easily as a pair of gloves with spandex or other synthetic material included, if you get the right size, they are very comfortable to wear.
Durability
These gloves are relatively lightweight, and their overall durability does leave a bit to be desired. Quite a number of people found that they were easy to tear on objects such as keys, fishing hooks, and tent spikes to name a few. While they are fine as liner gloves and work very well for that purpose, we wouldn’t suggest using them as your everyday outdoor activity gloves.
Summary
If you’re looking for a pair of liner gloves that will help you keep your hands warm and relatively dry, this pair from Terramar will certainly fit the bill. While the durability could be a bit better, overall they serve their purpose well.
13. Carhartt Base Force Top
One of our personal favorites for staying warm is the Carhartt crewneck top. While it may be a little stiff and uncomfortable right out of the box, over time the cotton knit thermal shirt will become your favorite, without any question.
Read moreOverall Fit
The majority of the people who bought this shirt found it to be a comfortable, if slightly snug fit. A small minority found that the shirt was a little too restrictive in the shoulder and upper arm area, but overall, there weren’t too many complaints as far as size was concerned.
Comfort
When this shirt is first worn, many people find it to be unnaturally stiff and unyielding. However, after a few wash and wears, the close-knit cotton fibers begin to become more flexible and giving.
Weather Resistance
In addition to helping you conserve body heat, this shirt is always quite good at keeping moisture and sweat away from your body using a moisture-wicking cotton knit material. Also, the material has been designed to help repel stains and dirt, which can shorten the life of any shirt, thermal or otherwise.
Materials
This shirt is made from a 100% cotton blend material that stretches over time to fit comfortably in nearly every situation.
Durability
This shirt is machine washable, and the knit design actually helps to release stains in the wash, so it’s fairly easy to keep clean. You can expect it to last for a decent amount of time.
Summary
If you’re looking for a shirt that can help keep you dry and warm even on the worst winter day, this choice from Carhartt is an easy one to make.
14. DG Hill Insulated Socks

Durability

Summary
These socks are priced well, comfortable, and provide great warmth. What makes it even better is that each pack comes with two pairs and are available in multiple colors. If you’re looking for that extra layer of coziness this winter, this is a great choice.
