Your Perfect Guide To The Best Sleeping Bag Liner

When you are going on an outdoor adventure such as backpacking, hiking, or camping, one of the items that you should bring with you is a sleeping bag liner that you can use as your stand-alone sleeping bag during warm nights or an addition to your sleep system.

The great thing about many sleeping bag liners is that they are very small and lightweight which is a very important feature when you are going on an outdoor journey.

However, sleeping bag liners have differences which will make you dissatisfied if you don't choose the best sleeping bag liner and if you purchase the product that doesn't fit your needs and your preference.

To help you decide which sleeping bag to purchase, I listed and reviewed in this article each excellent sleeping bag liner that is currently available on the market.

Why Should You Buy Sleeping Bag Liners?

If you travel frequently, you might be going from hostel to another to sleep. There are also a lot of other travelers like you who do the same thing, so imagine how many sleepers occupy the beddings of these hostels each day.

Just thinking about this fact makes cleanliness of these beddings questionable.

However, with the use of bag liners, you can keep yourself separated from these beddings which possibly also have bedbug infestations. For this reason, many hostels also require visitors to bring their sleeping bag liner.

As a backpacker, however, you surely know how difficult it is to clean a sleeping bag; however, you still have to maintain it for a less stressful sleep. You can eliminate this work by getting a sleeping liner which is a lot easier to clean than a sleeping bag.

Because sleeping bag liners reduce the need to wash your sleeping bag, it also allows your sleeping bag to live longer.

Without a doubt, buying a sleeping bag liner saves you time and effort while offering a clean thing to sleep on as well. However, its most important benefit is warmth.

Having a 3 or 4 season sleeping bag does not guarantee that you will feel the heat that you will have a cozy and warm enough sleep especially when the temperature begins to drop quickly.

Sleeping bag liners will surely enhance the heat that you feel and add to the warmth that your sleeping bag already gives.

At times, if you want to adjust the heat that you feel, you need necessarily bring another sleeping bag but just another sleeping bag liner which is a lot more portable and lighter.

Sleeping bag liner is also one of the most versatile outdoor equipment I have come across. You can use it on top of a sleeping bag or inside it. You can also use it as a stand-alone sheet.

Here is a good video about that will help you understand why sleeping bag liners are important on your trip:

Things to Consider When Purchasing A Sleeping Bag Liner

After learning the best products to choose from as well as their pros and cons, you probably already know which among the four items in our list is worth-buying based on your outdoor needs.

Before making an order, however, it is necessary to find out the things you have to take into account when getting a sleeping bag liner.​

Remember this item will cost you money, and you just want to get one that is worth every penny. Do not worry as I will discuss each of this features thoroughly.

Materials

There are various types of materials manufacturers use in making sleeping bag liners, but the first consideration when selecting which one to buy is the climate of the place where you plan to camp or hike.

Some liners utilize silk. These sleeping bags are the best to use during summer conditions. They are also lightweight (one usually weighs 5 oz.); however, if you want extra warmth, it is not something that I would advise you to use.

Fleece line liners, on the other hand, are ideal to use if you want to do your adventure in cool places. It is soft, and it dries quickly. It also wicks moisture away. However, you might find the average- and heavy-weight a little bulky.

Some sleeping bag liners use cotton which is absorbent, strong, and durable. Sleeping bag liners that use cotton are among the most economical items that you can find.

You can also rely on an insulated liner if you want to increase the inside temperature of your sleeping. This type can add up to 12°F to 25°F of heat.

Polyester is light and durable; however, they may not be the most comfortable materials against the skin that you can find.

Polycotton is a combination of the breathability and softness of cotton and strength of polyester. It is lighter compared to cotton, but one thing I love about it is that it is very quick and easy to clean.

For humid conditions, the bag liners that I would recommend are the synthetics which are both breathable and moisture-wicking. Also, they give some stretch which is just perfect to use if you are someone who sleeps restlessly.

Fit

One thing you will find out when buying a sleeping bag liner is that they come in various shapes. Some manufacturers make and design sleeping liners that are for people of average height. However, some hikers and campers have considerably shorter or larger.

The good news is that manufacturers also come up with sleeping bags that are either too long or too short to accommodate these people.

Shape

There are two main shapes of sleeping bag liners, and it is important to know how they are different from each other to help you decide which you think is more suitable for you.

The first shape is the standard or rectangular shape. It fits almost all types of rectangular sleeping bags, and its sides are straight as well. The second shape is the mummy style which is thin at the feet and wide at the shoulders, giving a snug fit. Some mummy liners also have hoods which provide additional head coverage when necessary.

Warmth

Even sleeping bags that are thin will surely add warmth to your sleepings bag. However, when sleeping outside during snow season, thin materials may not work. For this reason, it is always crucial to check the materials that make up your sleeping bag liner and know which one will make you stay warm.

As with any products, thick materials are warmer compared to thin ones. Temperature ratings will also be a lot helpful when deciding if the liner that you intend to buy will provide you enough amount of warmth during your trip, so make sure to see if your liner has one.

Price

My last consideration when shopping for a sleeping bag liner is the price. I honestly do not mind buying a bit expensive liners as long as they will keep me warm.

Whether a sleeping bag liner will be pricey or not often depends on their fabrics. Insulated, or silk liners are the most costly that you can find. Meanwhile, cotton cost the least. Microfleece or synthetic fabrics are moderately priced.

Brand name also affects the price. One tip that I can give if you have a limited budget is to assess the types of materials that you can buy and select from based on the anticipated temperatures; afterward, you can decide after knowing the price of each.

Other features

After understanding the basic considerations when buying sleeping bag liners, you may also want to consider few other features which will surely enhance your outdoor sleeping experience.

If you own a winter sleeping bag, it perhaps contains a hood which makes your head feel warmer at night. I suggest that you pair this with a sleeping liner that also has this excellent head covering when it is freezing to have the best insulation possible.

Did you know that some sleeping bag liners have a bug-repellent coating? These types of liners are extremely helpful to stay away from biting insects and mosquitoes when hiking or camping in humid areas.​

Last is a pillowcase liner. Often, bringing your comfortable backpacking pillow may not be a problem; however, there may be times when you forget to bring one, or just intend not to carry them because you already have too much to bring.

So, you just borrow one from your fellow hiker, but you are not sure how clean it is. However, some sleeping bag liners come with sleeping case liner which keeps pillows of questionable cleanliness from touching your skin.

Conclusion:

All of these sleeping bag liners are great options as they can all help you keep your sleeping bag clean. I suggest that you think carefully about the important considerations that we mentioned before landing on a decision to have the right sleeping bag liner for you.

Anyways, you can always check this review as your guide.

Even though these products I reviewed are all working at their best, if I were to choose which product is the best sleeping bag liner for anyone, I would select Bundle Monster Microfiber Fleece Sleeping Bag Liner.

I said so because of its relatively high warmth rating, flexible sleeping arrangement, and reasonable price. On top of these features, this sleeping bag liner is very versatile since it also fits not only my sleeping bag but also my dearest hammock.
