Sleeping bag liners are popular items to make sleeping bags warmer in colder weather. People often question whether or not they are effective. The answer is that they can be effective but it depends on a variety of factors.
Sleeping Bag Liner Materials
Different sleeping bag material liners will have different levels of increasing the warmth of the sleeping bag. There are pros and cons to each type of liner. Take a look at the following:
Silk Sleeping Bag Liners
Silk sleeping bag liners are soft, light, and compact. In addition to providing warmth, they help to keep your sleeping bag clean. They are easy to take camping because they are so compact. Silk breathes well, wicks moisture, and provides some warmth.
Cotton Sleeping Bag Liners
Cotton sleeping bag liners are bulkier than other types and they don’t wick moisture away very well. They are good for traveling, easy to wash, and provide a little bit of extra warmth.
Microfiber or Microfleece Sleeping Bag Liners
These sleeping bag liners are made with materials that are great for comfort and protection. As with silk, they will provide minimal warmth.
Merino Wool Sleeping Bag Liners
Merino wool can be expensive but it does wick away moisture and it is very soft. They will add warmth to the sleeping bag as well.
Thermal Synthetic Sleeping Bag Liners
These sleeping bag liners provide the most warmth and they come with varying fills. They wick away moisture, are breathable, and add comfort to your sleeping bag. These are the best liners for warmth.
Why Do People Use Sleeping Bag Liners?
Although one reason why people use sleeping bag liners is for additional warmth when camping during cold weather, there are other beneficial reasons to use them. They can help to keep your sleeping bag clean, which will make it last longer. It is easy to remove the liner and wash it after a camping trip.
In addition, people use the liner alone without a sleeping bag during the hotter months in the summer. Sometimes it is too hot to sleep in a sleeping bag and this is a great alternative.
When you sleep in a sleeping bag, you bring all kinds of dirt and debris from the outdoors inside. If you sweat during the night, the sleeping bag will absorb your sweat and other body oils.
This makes using a liner very advantageous as you can wash it and protect your sleeping bag.
Alternatives to Sleeping Bag Liners
If you want to have the benefits of a sleeping bag liner without using one, there are ways to do this. One option is to bring clean clothing to use when you sleep. If you have thermal underwear, you will stay warm and protect your sleeping bag at the same time.
In addition, you won’t have to worry about the sleeping bag liner being tangled up around your feet if you move around while you sleep.
When you are camping with a tent, you can take steps to keep your tent warm, which will minimize your need for the sleeping bag liner. You can also use a sleeping bag pad for added comfort.
Finally, if you want to make your own sleeping bag liner, you can do so using various materials. If you are hiking while you camp, you will want to use thin materials that pack easily so that you won’t have to carry too much with you.
Final Verdict: Are Sleeping Bag Liners Worthwhile?
There are people who swear by sleeping bag liners and others can’t stand them. It really is a matter of personal preference. They can definitely add warmth and comfort to your sleeping bag.
If you are hiking, you should look into more compact materials such as silk. If you are camping during colder temperatures, thermal synthetic liners can be great for warmth, moisture absorption, and comfort.
One huge benefit is that you can have one sleeping bag for all seasons and use the sleeping bag liner as needed. You can use the liner without the sleeping bag in the summer, use the sleeping bag alone in the fall and spring, and use it with the liner during the winter.
You will make your sleeping bag more versatile by having the liner available.
