Okay, we know they aren't the most popular piece of camping gear to talk about, but sleeping bag liners are essential in environments that are either extremely cold or extremely warm. There are a lot of seasoned travelers who wouldn't consider going anywhere without one.
Because they provide an additional layer of warmth as an inner lining of a sleeping bag or between you and the blankets on a bed, a quality sleeping bag liner is well worth its (very little) weight in gold when traveling to locations with lower than average temperatures.
They can also perform as a lightweight travel sheet that will give you a decent night's sleep in tropical areas, whether you are staying in a hostel, riding on a train, or even camping in the jungle. So even if you aren't able to carry a full pack of camping gear with a sleeping bag, having a small lightweight sleeping bag liner still provides you with the clean comfort of being in your own environment.
Convinced? Awesome! We've done a lot of research for you and have come up with a few choices to make it easier for you to pick the best sleeping bag liner for your next outdoor adventure.
How to Choose the Best Sleeping Bag Liner?
Most Important Characteristics to Consider
A wide variety of materials are available for sleeping bag liners. Each of these materials comes with its own set of advantages and limitations.
Silk, cotton, fleece, microfiber, and synthetic materials are used. Which material you choose will depend on a few things:
- some materials are more lightweight, so suitable for backpacking or taking in a suitcase.
- others materials are better suited to keep you warm, or cool.
TEMPERATURE | R-VALUE
Most manufacturers will include a temperature value on their sleeping bag liners. Winter sleeping bag liners, will have temperature ratings based on the temperatures they will be most effectively used. They often have a plus sign before their rating. This grade indicates the number of degrees of warmth that the liner ought to provide to your system.
The R-value provides a more straightforward reference for determining the level of warmth. The R-value of an object is a measurement of how well it can prevent heat from passing through it. A warmer sleeping bag liner has a higher R-value because it provides a higher level of insulation and may prevent heat loss.
SHAPE and LENGTH
Sleeping bag liners may be rectangular or mummy-shaped, much like sleeping bags. Investing in a sleeping bag liner that conforms to the specific contours of your sleeping bag itself is your best option. Also consider the length of the sleeping bag liner; if it is too short or too long, it will not be as effective.
If you lose heat from your head throughout the night when camping, it won't matter how warm your sleeping setup is; you'll feel cold. Lots of sleeping bags come with hoods, so if your sleeping bag has a hood, order a sleeping bag liner that also has a hood.
Maybe even consider a sleeping bag liner with a hood even if your current sleeping bag doesn't have a hood. At least you would have one extra layer of warmth.
Before purchasing any equipment, consider if you will be hiking for long distances with your gear, or will you be car camping, where the weight and size won't matter as much?
You might have to compromise on weight and pack size vs warmth.
But there you have it. Make your decision based on your intended use and choose the right material, size and weight to fit your sleeping bag.

There is a solid reason why the Sea to Summit Reactor Thermo light Insulated Liner is one of the most well-liked and best-selling sleeping bag liners available on the market.
We like the Reactor Thermo light fabric, it's truly the liners unique feature. It is designed with hollow core fibers and is composed entirely of polyester, both used so this sleeping bag liner can keep you super warm.

Litume began as a modest family company and has gradually expanded its assortment of high-performance outdoor goods. Their sleeping bags and liners are outstanding, and this is just one of four sleeping bag liners available.
The Litume Thermolite All Season Sleeping Bag Liner is a great way to warm up and get comfortable in your sleeping bag. We like how it can cinch up around your face, which is ideal for the winter when the air is freezing your cheeks off.
The Thermolite type can add up to 27°F / 15°C to your sleeping bag and is even warmer with the fleece lining.
The Thermolite sleeping bag liner employs hollow fiber technology to retain warm air and promote moisture wicking.
It is made of the same exceptionally soft and elastic bag liner material as several of the Sea to Summit Reactor series.
The well-defined and distinct foot area keeps everything in place so you don't get all twisted up, which is beneficial.

It makes it simple to get in and out of the liner, and when unzipped, it functions as a single massive sheet.

FAQs About Sleeping Bag Liners:
Is It Worth It To Buy Sleeping Bag Liners?
Yes, they are worth it. When camping in cold areas sleeping bag liners are undoubtedly worth it. A sleeping bag liner will give you much-needed warmth if your tent doesn't have a heater.
We also like sleeping bag liners for protection and use in hotel rooms, youth hostels, cottages or cabins to cover the sheets or old mattresses. It's an easy way to protect yourself and sleep more soundly.
Which Is Better for Sleeping Bag Liners: Silk or Cotton?
Both silk and cotton sleeping bag liners have their benefits and drawbacks. So the answer to this question largely depends on personal preference. Some people like silk liners because they feel smoother and cooler against their skin, while others prefer cotton liners because they are more absorbent and comfortable. Ultimately, it comes down to what you prefer.
Is a fleece sleeping bag liner suitable for backpacking?
Yes, a fleece sleeping bag liner can be a suitable option for backpacking, but it will add some extra weight to your pack. A fleece sleeping bag liner can provide an extra layer of warmth on colder nights, and it can also help to keep your sleeping bag clean. If you're looking for a lighter option, you might consider using a synthetic sleeping bag liner instead of a fleece liner.
