Why You Should Get a Cold-Weather Sleeping Bag
Sleeping bags are made for different temperatures and climates. Cold-weather bags are better insulated and created for the purpose of camping in harsh weather. The main advantage of a cold-weather bag is that it increases the camping season for you and will no longer be restrained by the plummeting temperatures outside.

Alternatively, a sleeping bag that is rated for colder weather can be a good choice for sleeping under the stars. If you are hiking and want to travel light, or just enjoy sleeping under the stars, a cold-weather bag might allow you to forgo a tent or shelter. If you usually employ the combination of a regular bag and a tent to keep warm, then the cold-weather bag alone may get the job done.
You always want to use the correct tool for any job. If you select the wrong sleeping bag, it can lead to a miserable trip. You will be spending a lot of time in your sleeping bag, so you want to be sure to get one that matches the environment you camp in.
Things to Look For When Buying a Sleeping Bag
When you select a sleeping bag, there are a number of things to consider. Price, quality, shape, and size are all important. You will want to check the sleeping bag’s temperature rating, build materials and features as well.
One of the first things to consider is the temperature rating of the sleeping bag. The ratings show the lowest temperature that the bag should keep you comfortable in. For example, a 20-degree bag will allow you to sleep in comfort as long as the temperature stays at 20 degrees or above. The ratings assume the user will be wearing warm attire and using a pad underneath the bag.
For a consistent standard on temperature ratings, look for a seal or tag that says the bag is EN tested. EN is short for European Norm. This is a set of criteria for rating the sleeping bags. Keep in mind your tolerance for the cold. Everyone is different in how comfortable they can be at various temperatures. You need to consider this when looking at the temperature ratings. No rating system is infallible. They are not exact measurements meant to be followed precisely but think of them as a general guide.
Do proper research and make sure you understand the environment you will be camping in. Select a sleeping bag that will handle the coldest temperatures possible, from extreme cold weather sleeping bags to a summer bag. It is often a good idea to choose something rated for more frigid temperatures than what you believe is necessary. If you get too hot while sleeping, you can always unzip the bag and get cooler. For cold weather, mummy-style bags are usually recommended.
Your next choice should be the type of insulation. For cold weather, it is often advised to avoid cotton. Feather down provides excellent warmth and quality. Synthetic fibers can provide strength, durability and some level of water resistance. Many bags use a mixture of materials. If you are conscious about the issue of using a down-filled bag, then look for companies that ethically source the material. Goose down often provides better insulation than duck down. This is something to be aware of when comparing models. Not only does the filler affect the warmth factor, but it changes how comfortable your bag will be as well.
The shape of your sleeping bag is an important factor in how it will work for you. The size of your sleeping bag also contributes to its effectiveness. The correct size should be form fitting. If the bag is too big, this will harm its efficacy at insulating you. You don’t want it to be uncomfortably small, but it should be snug for maximum warmth. For ladies, sleeping bags are produced specially to fit the contours of a woman. These may be more comfortable for you.
The main shapes are the mummy and rectangular. The two most common forms of a sleeping bag are rectangular and the mummy. A rectangular bag is your common sleeping bag that is suitable for regular weather. The mummy-style bags offer more protection for your head during colder temperatures. Most cold-weather sleeping bags come in this shape.
Rectangular bags may allow more room to move around in, but Mummy bags tend to offer better insulation and prevent heat from escaping through your head. However, if you are a bit claustrophobic, then a mummy bag may not be the best choice for you.
The weight of your sleeping bag should be a consideration if you plan on hiking. This can be a delicate balancing act. You need to weigh the need for warmth against the inconvenience of carrying heavy gear. Protection from the cold should always take precedence. Try to select a bag that will fit your body correctly. Many manufacturers only offer bags in a few sizes such as small, large and extra-large. Check the packaging for information on each size and the heights they are built to accommodate.
Outer Shell Material
The insulation material is not the only thing to pay attention to while shopping for a sleeping bag. Most of the bags externals will be made of nylon or polyester. Pay attention to the stitching and thickness of the materials. If you are camping in damp environments, look for a bag that has is water-resistant.
One of the most important features to take note of is the zipper. Some sleeping bags forgo having a zipper at all. These may be better at keeping you warm, but they can be challenging to get in and out of quickly. Check to make sure the zippers are of a high quality. A good sleeping bag may include a draft tube. This is an insulated tube that is designed to keep heat from escaping through the zipper.
For cold-weather mummy bags, they will feature a hood to protect your head from the cold air. This is the area that closes around your head to prevent heat from escaping. Pay attention to how the drawstrings are constructed. Face mufflers, draft collars or neck baffles are all good features to have. These add further protection from the cold for your neck and head areas.
A low price may seem like a bargain at the store. It will seem less so if you end up freezing in the wild or watching the bag easily tear with normal use. Compare prices with bags that have similar features, but do not necessarily go for the lowest cost. Your sleeping bag is one of the most important pieces of gear you’ll use while camping.
Get the Most From Your Sleeping Bag
Once you purchase your sleeping bag, there are a few things to remember to get the most out of it. You never want to place your sleeping bag directly on the ground. A pad should be used to prevent the ground from quickly cooling the bag. This is less necessary when sleeping inside of a tent with a floor, but still not a bad idea.You can warm the sleeping bag throughout the day by placing it in the sun or close to a campfire. This may get you some extra warmth for the first hour or two of your sleep. Using hot-water bottles is another method of keeping even warmer. If you have trouble finding a sleeping bag that fits snugly, you can always stuff extra clothing or materials into your bag. This negates any air pockets and keeps your own body heat close to you. It’s important to take care of your sleeping bag so that it provides years of use. Store your bags in a dry area. It is a good idea to store them uncompressed, so the filling doesn’t get bunched up and crushed. Clean your sleeping bags after every use. Be sure to clean and dry them as soon as possible if they get wet on your camping trip.
