Factors to Consider: Cold Weather Sleeping Bags Buying Guide

It’s great if you read other reviews to find the ideal backpacking sleeping bag for your needs, especially if those reviews are written by other customers. You do need to focus on the more important factors.

It’s not just all about the price, since your safety and comfort are more important factors compared to the few dollars you can save. Still, you can find the best budget sleeping bag that can meet both your needs and your budget limitations.

Fashion and good looks are also not terribly important, though there are sleeping bags for girls which look quite feminine even as they’re terrifically functional.

Here are the considerations that should be uppermost in your mind:

Temperature Rating

One of the main problems looking for the best sleeping bag for camping is that there’s no standard temperature rating system that all manufacturers follow. However, some manufacturers do specify the seasons for which their sleeping bags are designed:

  • Cold weather sleeping bags. These are meant for extreme temperatures that can go down to 20° F and below. If you’re going camping in winter in high altitude places, then you definitely need these sleeping bags. Check out more zero-degree sleeping bags here.
  • 3-season sleeping bags. These may not be perfect for all climates, but they work very well for temperatures hovering at the 20° F level. A typical 20-degree sleeping bag often features zipper draft tubes, draft collars, and hoods that you can cinch tightly.
  • 2-season sleeping bags. A bag like this is often called a summer sleeping bag since they’re often best for warm temperatures at around 32° F. They’re not exactly ideal for colder weather. 

If you’re partial to sleeping bags made in Europe, then you may notice how they may follow the European standard for labeling sleeping bags. This is called the EN13537 rating:

  • Extreme. This type of bag that can ensure your survival in extremely cold weather as it keeps you from freezing to death. Still, it also means you won’t be terribly comfortable.
  • Limit of comfort. This rating means that the bag can not only let you live on cold weather, but if you’re a man then you can even sleep comfortably at night.
  • Comfort. This is the warmest of these sleeping bags, since it enables even women to sleep comfortably even during the coldest weather. Not to be sexist, but on average women simply need more insulation than men to stay warm.

Type of Insulation

The best sleeping bags for cold weather generally have 2 fabric layers. You have the shell fabric on the outside and the lining on the inside. In between these 2 layers is the insulation, which can be made of natural down or synthetic materials.

Down sleeping bags require a smaller amount of insulation to provide the same warmth as a larger synthetic insulation. This is why the compact sleeping bag often uses down insulation. You get a compact cold weather sleeping bag that can fit in nicely at the bottom of your backpack.

Down material can be quite a bit more expensive than even the costliest synthetic material, but at least it’s a good investment as it can be expected to last for many years. Although down generally loses its insulating ability when it gets wet, manufacturers avoid this problem by treating the down with long-term water repellant.

Check out the fill power index of the down sleeping bag, which will range from 400 to 900. You’ll want the fill power as high as you can get so you can get the most warmth with the least weight.

Those who are looking for a lightweight sleeping bag that’s also light on the wallet should opt for a synthetic sleeping bag. These aren’t just inexpensive, but they can insulate even when wet and they can dry very easily. Some people are also somewhat allergic to natural down, so they’re better off with synthetic insulation.

On the downside, synthetic sleeping bags don’t compress very easily. So they can be somewhat bulkier in comparison to down sleeping bags.

Size and Shape

Often you can find backpacking sleeping bags available in sizes for both men and women. The sizes can include short (66 inches), average (72 inches) and tall (78 inches).

Shapes can also vary:

  • Rectangle. These are very roomy sleeping bags, and two of these rectangle sleeping bags may be joined to have enough space for two people to sleep together.
  • Mummy. The shape is wide at the shoulders and narrow towards the feet. They’re more restrictive, but they can be much warmer as there’s less air to heat.
  • Tapered rectangular. It’s a design that combines features of the rectangle and the mummy. It’s somewhat tapered, but you still have room to move and maneuver to a comfy sleeping position.
  • Women-specific. These are shorter bags that are narrower at the shoulders and wider at the hips. Often they come with additional insulation for the footbox and the upper body.

Water Resistance

Hypothermia can be a serious problem in cold environments, so you really don’t want to get wet while you’re sleeping at a campsite. Some bags are water-resistant, but others are deemed waterproof.

Portability

This takes into account the weight and bulk of the sleeping bag. An ultralight backpacking sleeping bag can weigh in at just 1 pound while others aren’t really all that heavy at 3 pounds or more.

You have to remember that you will have to carry your sleeping bag, so you should get the best lightweight sleeping bag that can provide the necessary warmth. A lightweight compact sleeping bag can be terrific, so you have more space in your backpack for more gear.

Convenient Features

Once you’ve taken care of the basics, you should see what other features you can enjoy from hiking sleeping bags. The features you may like can include:

  • Polyester or nylon lining. These types of lining draw away moisture, unlike cotton which can leave you feeling uncomfortably damp.
  • High quality zippers. The zippers should be on both the outside and on the side, so you can enter or leave the sleeping bag easily when you’re on your own. The zippers should slide easily and it should go all the way around so you can open the bag completely when you’re using it for warmer weather.
  • Neck collar. This is great for a cold weather sleeping bag as this keeps the heat from escaping from the neck of the sleeping bag.
  • Hood. A built-in hood keeps your head warm especially when you cinch it tight with a draw cord. Some hoods even have a pillow pocket, which you can stuff with some cloth to form a makeshift pillow.
  • Sleeping pad sleeve. This lets you move without having to roll off the sleep pad in the middle of your sleep.
  • Pockets. These can let you store items like your smartphone on the inside, so you can use them without having to unzip the sleeping bag and letting all the heat out.

All these considerations must be factored in when you read the many sleeping bag reviews from customers. That will take time, but you can accelerate your search for the warmest sleeping bag by focusing on our recommendations:

The TETON Sports Deer Hunter Sleeping Bag; Warm and Comfortable Sleeping Bag Great for Fishing, Hunting, and Camping; Great for When it’s Cold Outdoors is one of those specialty sleeping bags that cater for rather specific needs. Anglers and hunters in particular may have special requirements that regular backpackers don’t need.

This is in fact for extreme weather conditions, when you’re hunting in higher altitudes or fishing in ice holes during winter. That’s what it’s rated not just for temperatures of zero degree F. Instead, it’s actually able to let you survive temperatures down to minus 35 degrees F.

Its warmth rating is fantastic, with about 20 to 30 degrees higher than what you’d get with other sleeping bags. To achieve this, it uses special fiber fill for insulation and it comes with double layer construction. It also has zipper and shoulder draft tubes working in tandem so that the heat stays in and the cold stays out.

You don’t even get chilly spots as the seams are staggered so that the fill can be distributed evenly. With the warm flannel lining, you’ll feel nice and comfy as it retains body heat. You won’t get wet either, as the outer shell is thick and water resistant.

If you’re concerned about it being too warm, don’t be. The zippers open at the top or bottom so you can adjust the ventilation. The zippers are also self-repairing, and they don’t snag.

In fact, the zippers even allow for a second sleeping bag to be attached to the first, so the occupants can share sleeping space. Not that a single bag is too snug—it is 90 inches long and 39 inches wide. It’s like sleeping on a twin mattress.

It comes with numerous features that ensure you stay warm even during a night spent outdoors. It has Thermolock draft tubes for warmth and retaining heat, as the warmth can’t seep through the zipper.

The 600 fill power down can keep you quite warm, and it’s rated for temperatures down to 15 degrees F. Like you’d expect from what many consider their best sleeping bag, it’s durable enough to warrant a limited lifetime warranty.

There’s also a draft collar that just wraps around your neck automatically. The hood is contoured and also fully insulated, and you can cinch it down so you keep your head warm too.

Get the XL, and you’ll have lots of extra breathing space so you don’t feel claustrophobic. It is even 3 inches wider than many other sleeping bags, measuring 87 inches by 33 inches. What’s more, the zipper has an attachable design so that you can have 2 of these bags attached together. This can then be compressed for greater portability.

The outside of the bag is waterproof yet also breathable. Inside you’re comfortably warm, while the lining feels friendly for your skin. There’s no cheap feel to this sleeping bag, though its price is generously affordable. In fact, you can buy for each family member and your total costs may not even exceed the price of a single premium sleeping bag.

Yet this offers premium comfort and convenience. You’ve got an adjustable hood for your head and an extra zipper on the bottom for more space (or ventilation) for your feet.
