Regardless of whether a consumer is a traveler or someone who spends a considerable amount of time traveling, they’re probably going to want to get a sleeping bag liner. These liners, also known as travel sheets, are good for travelers who spend a lot of time in hostels or budget hotels, and is also good for campers who want to keep their sleeping bag in good conditioner longer. Since there are several different varieties of these liners available, we thought that we’d find out which models were the best sleeping bag liners and which ones the consumer should take a hard pass on. Let’s dig a little bit deeper into this subject and find out all we can about these travel sheets.

Quick Summary of the Best Sleeping Bag Liners

Best Overall: Sea To Summit Lightweight Reactor Liner

This liner from Sea To Summit isn’t your average set of travel sheets. It’s not just designed to put a layer of protection against whatever sheets the traveler is going to use them on, but it’s also designed to keep the user warm in cold weather. It’s a product that’s made out of polyester and has a mummy shape that’s equipped with a foot box. It also features a drawcord hood and mini-cord lock. All of these features come together to help the traveler or camper stay warm during cold conditions. When this sleeping bag liner is equipped into a standard sleeping bag, it will add up to 14-degrees of temperature to the bag. Many times, that’s just enough of temperature rise to keep the camper safer in cold weather conditions.

Because this product is made from polyester and not from fleece, it’s lighter and easier to carry. It can be packed down to a 3×5-inch size and only weighs approximately 9-ounces, so it can be taken anywhere. It’s also easier to wash than fleece and will help keep the user’s sleeping bag cleaner for longer periods. Although this liner does cost more than some of its competitors, we feel that this is the best sleeping bag liner currently available and is a must-have for any camper, traveler, or anyone who needs a liner for their emergency sleeping bag. It’s a liner that we think is going to serve a lot of people well.

What we liked about it
  • It helps keep the user warm.
  • It’s very comfortable.

Best Lightweight Liner: The Friendly Swede Camping Sheet

Dirty hotel or hostel sheets and soiled sleeping bags don’t have to be a constant worry of the traveler or camper any longer. At least, not when they have one of these liners to sleep in their sleeping bag. Regardless of whether this liner is used to protect the user against questionable sheets in sub-par hotels or motels, or whether it’s slipped into a sleeping bag and used out in the wild, the consumer is going to find that this product gives them exactly what they need. This liner has an overall size of 41×86-inches, with a body compartment of 66.5-inches when you subtract the pillow pocket. This liner is durable, made of machine-washable polyester and will keep the consumer comfortable all night long.

Since this bag only weighs about 8.35 ounces or about the weight of two sticks of butter, it’s easy to take just about anywhere. It’s equipped with a 23-inch left-side opening that makes it easy for the traveler or camper to slip in and out of, and it has a texture that is as soft as silk. The model we reviewed had a velcro closure that was easy to use, but some models are equipped with a zipper. Of course, the ones with zippers weigh a little bit more, but only a little bit. Even though this product might be a little short for consumers who are over 6-feet tall, we feel that for average size or shorter individuals, these liners are some of the best ones to own.

What we liked about it
  • It’s comfortable to sleep in.
  • It’s easy to get in and out of.

Best Cold Weather Liner: Outdoor Vitals Sleeping Bag Liner

For autumn or winter weather, this sleeping bag liner is just what the proverbial doctor ordered. It’s manufactured from a micro-polyester that’s comfortable against a person’s skin, weighs only a few ounces, but provides the user with a much-needed layer of insulation. It’s an insulation that will keep the sleeper warm on cold nights, and can also be used as a barrier for when a traveler is sleeping on the questionable bedding of hostels or budget hotels. Although this liner might be a little too warm for sleepers who want to use it during the humid summer months, we feel that for the rest of the year it’s a good travel sheet for anyone to use and enjoy.

This liner is easy enough for most people to fold into a small size and packed into a backpack, so it can be carried virtually anywhere. Another thing that we liked about this sleep liner is that it was easy to maintain. Whenever the user needs to clean it, all they have to do is throw it in their washing machine and then dry it. It’s then ready to go. The rectangular version and the mummy versions of these sleeping bag liners are 80×32-inches in size and they weigh approximately 8-ounces. And because this liner is backed by a limited lifetime warranty from the manufacturer, the consumer can count on it lasting through many, many camping seasons.

What we liked about it
  • It helps to keep the consumer warm.
  • This liner is nice and soft.

Best Warm Weather Liner: Vumos Camping Sheet With Full-Length Zipper

Before we get too deep into the review for this Vumos sleeping bag liner, let’s address the elephant in the room, which is this camping sheet’s suitability for cold weather. Although we found that this camping sheet did an amazing job in temperatures 45-degrees Fahrenheit or higher, this product didn’t provide the necessary insulation for any weather colder than that. And that’s okay because this is primarily a summer camping sheet that’s designed to put a surface between the camper and the sleeping bag, or for travelers who need to use it as a travel blanket. If consumers can keep in mind that this isn’t a cold-weather sleeping bag liner, then they’ll appreciate it all the more.

The one thing that we liked about this product was that it was super soft and very comfortable to sleep in. It’s made from 100% polyester, but it has a silk finish to it that just feels lightweight and breathable. This liner is approximately 85×33.5-inches, weighs only 11.5-ounces, and is capable of being packed down to 7.5-inches. That makes it easy to pack into a backpack or duffle bag, and also makes it easy to transport. It also comes with a little pouch that can be used to store or transport this liner. And because it’s backed by a limited lifetime warranty, this product should also last the user quite a long time.

What we liked about it
  • It’s a lightweight mild-weather sleeping bag liner.
  • It’s soft and extremely comfortable.

A Guide To Sleeping Bag Liners

It should go without saying that sleeping bag liners are extremely important pieces of equipment for both travelers and campers. Without these liners, the traveler would have to deal with sleeping on questionable sheets at hostels, motels, or hotels, and for campers, it helps them to keep their sleeping bags in better condition and can also add a bit of warmth. To help our readers not only discover the best sleeping bag liners available but also use them correctly, we’ve decided to write this informative guide on the subject.

Choose The Appropriate Liner Shape

One of the first things that the consumer is going to want to consider is the shape of the liner. Most liners come in either a mummy-shape or a rectangular shape, and each of these different shapes serves a specific purpose. For example, mummy-shaped bags are the ones most likely used by campers for inserting into their sleeping bags. For travelers, rectangular-shaped liners are usually the best. Therefore, the consumer should choose the shape of the liner that’s the most appropriate for the liner’s ultimate purpose.

Make Sure To Find The Right Size

Sleeping bag liners come in a variety of different sizes, but most of them are in the 80-85-inch length range. That’s the average length of most liners. That makes them appropriate for most people. However, some liners are smaller than that, which might pose a challenge for taller travelers or campers. Therefore, if the person is taller than average, then they might want to pay special attention to the liner’s size to make sure that they will fit comfortably in it.

The Liner’s Material Are Also Vitally Important

The next thing that the traveler and/or camper is going to want to seriously think about is the material that the liner is made out of. Although consumers had fewer options in the past as to what their sleeping bag liner was made from, they have many more options available to them nowadays. These liners are made out of everything from silk or cotton to fleece, synthetics and microfleece materials. Let’s take a closer look at each of these materials and see how they hold up to certain conditions and what their pros and cons are.


Although cotton sleeping bag liners aren’t as common as they used to be, some still use this material. Cotton is soft and allows air to pass through it, but it also absorbs moisture and that can cause it to get wet. The problem with it absorbing moisture is that it holds said moisture against the person’s skin, which can lower their body temperature and cause hypothermia. Therefore, cotton isn’t a material that a person who’s looking for a cold-weather liner is going to want to choose. The main benefit of cotton is that it’s cheap and lightweight.


Silk is a lightweight material that, like cotton, is very comfortable against the skin. It’s a material that’s capable of breathing in warm weather, but also helps to insulate during cold weather. Although silk does absorb moisture, unlike cotton it doesn’t hold that moisture against the skin and is capable of remaining warm. That makes it a good all-weather material, but we’d advise consumers who need cold-weather protection to choose another material altogether. Silk isn’t as cheap as cotton, but it’s not as expensive as some of the insulates either, so it’s a good middle-ground choice for some people.

Fleece And/Or Microfleece

As most people would probably guess, fleece and/or microfleece is a great choice for cold conditions. This material is capable of making a sleeping bag up to 12-15 degrees warmer, and it’s a material that very soft against the skin. Fleece and/or microfleece does wick-moisture away from the person’s skin as well, so sweat isn’t laying on them in cold conditions. Unlike cotton, however, fleece and/or microfleece doesn’t hold the moisture against the skin and dries quickly. These materials also have a moderate price. However, the main problem that fleece or microfleece sleeping bag liners have is that they tend to be bulky.

Polyester Synthetics

This category of materials includes a variety of polyester synthetics including materials such as Cool Max. This material allows air to pass through to the sleeper, and it wicks moisture away from the user’s skin. Because materials in this category are polyester blends, they tend to be hydrophobic, which means that they don’t hold onto moisture and dry quickly. This ability can make these good all-weather fabrics that have a moderate price tag. And because polyester is capable of stretching, most users find these bags to be more comfortable for sleeping.

Insulated Fabrics

Although these fabrics can be more expensive than other types, they are very warm and are capable of raising the temperature within a bag anywhere from 15 to 25-degrees Fahrenheit. This material also is moisture-wicking and dries 50% faster than cotton fabrics, so moisture won’t be held against the skin. Overall, this is a good material for use in cold-weather conditions, but as we said, it is a more expensive choice than fleece.
