Sleeping bag liners can add warmth and help keep your sleeping bag clean so you don’t have to wash it as often. It is much easier to throw a liner into the wash than a sleeping bag. When choosing a sleeping bag liner, the biggest choice you have to make is the type of material that is used to make the liner. The most common choices are silk, fleece, cotton, and wool.

Silk Sleeping Bag Liner:
A silk sleeping bag liner is lightweight and won’t take up much room in your backpack. It can also add a bit of extra warmth. However, if you’re buying a silk sleeping bag liner, you’re probably more interested in the luxurious feel of silk against your skin as you sleep. If you are used to using to silk sheets at home and want a taste of that luxury even while you are “roughing it,” a silk sleeping bag liner is a great choice. The biggest drawback to using a silk liner is that it becomes extremely uncomfortable if it gets damp, so if you are camping in an area where there is a lot of moisture, a cotton or fleece sleeping bag liner might be a better choice.
Fleece Sleeping Bag Liner:
If you are camping during the spring or fall when it gets cold at night, you will really appreciate the extra warmth provided by a fleece sleeping bag liner. No other material can top the coziness you’ll feel when snuggled up in a sleeping bag with a fleece liner. Fleece is much bulkier than silk or cotton though, so if you are hiking to get to your campsite and need to fit everything into a backpack, you might want to opt for a more compact sleeping bag liner.
Cotton Sleeping Bag Liner:
Using a cotton sleeping bag liner is a lot like having a cotton sheet between yourself and your blanket when you are sleeping in your bed at home, and the purpose is the same too. A cotton sleeping bag liner adds an extra layer that helps hold in the heat. It also helps keep the inside of your sleeping bag clean.
Wool Sleeping Bag Liner:
Wool is a warm fiber that many people prefer over fleece because it is natural. Like fleece sleeping bag liners, wool liners are very warm. However, a wool liner is usually quite a bit more expensive than a fleece sleeping bag liner. Many people also have a sensitivity to wool. If you are not sure whether you can tolerate wool close to your skin, it is better to choose another type of fabric or opt for a merino wool sleeping bag liner, which is made from softer wool fibers and is less likely to cause itching or discomfort.
Mummy Sleeping Bag Liner:
Now that you have decided what type of fabric you want, you still have one more choice to make. Do you want a mummy sleeping bag liner or a regular liner? A mummy-style liner is made to fit into a mummy sleeping bag. These sleeping bags are smaller at the feet and conform to the body’s shape more closely to provide more efficient heating. If you have a mummy sleeping bag, you will need a mummy liner too. However, even if you have a rectangular sleeping bag, a mummy sleeping bag liner will work with it, and this type of sleeping bag liner will usually keep you just a little bit warmer than a rectangular bag liner.
Using a sleeping bag liner with your sleeping bag is a good way to expand the temperature range in which the bag can be used so you don’t have to buy another sleeping bag. Regardless of which fabric you choose, you are likely to experience some discomfort if your sleeping bag and liner become wet, so choose your campsite carefully. Avoid pitching your tent in a low spot that is likely to accumulate water if there is a storm during the night.
