How To Choose The Best Sleeping Bag Liner – Buying Guide



As with any camping gear, weight is a key issue but especially more so if you’re going to be hiking. You want to be able to keep weight down to a minimum but also the size too as you need to ensure that all of your gear is going to be able to fit into your bag, so you can comfortably carry it to wherever you need to go.

All sleeping bag liners will be able to give you a layer of warmth but some are specifically designed for this while others are more geared towards simply giving you that protective layer. If you wanted the type of sleeping bag which is there to add warmth then this is going to be heavier as it would require more material for that insulation.

If you really wanted to pack light though then it makes sense to have a thinner sleeping liner which won’t be able to add much to the warmth but will have a very low weight but also have a smaller size too, which makes it easier to take from one place to the next.

As with a lot of camping products, there comes sacrifice with weight whether you are talking about having an ultralight tent, being able to cook on a portable grill or your liner. You have to determine how much you need to carry and what weight you need. If you’re going to be car camping or camping close to your car, then the weight is clearly going to be less of an issue.

Temperature Rating

The best sleeping bags on the market will be able to give you a great amount of warmth but there are reasons that you might want a liner for sleeping bags to give you an additional layer of insulation as, of course, the temperature isn’t going to be the same all year around unless you’re at the equator.

You may want to look at camping on every season, so you might need a layer of warmth in the winter that you didn’t need in the summer. If this is what you need then looking for sleeping bag liners which will be able to increase the temperature would be ideal and this will be displayed on the product listing.

It could also work the other way too. Getting a warm liner can actually work perfectly as a normal sleeping bag in warmer temperatures. Then during cold weather, you can then wrap up warm inside your sleeping bag. If this is what you require then just make sure that you check the temperature rating before buying the product.


Perhaps the most common material that can be found for sleeping bag liners is polyester which is a material that is found in all different types of camping gear due to its qualities. One of those qualities is the cost as they are relatively inexpensive which made them ideal.

Another material used for these types of liners is silk as a lot of people find that to be a very comfortable material in which to sleep. There are also plenty of liners out there made with synthetic materials which are designed to have a silk-feel to them, so you are able to get that comfortable feel.

Silk won’t provide a lot of insulation but it does have the quality of providing an extra layer of warmth when it is cold but it also won’t be too restrictive when it is warm either. Both polyester and silk can be made with a layer of ripstop in them which is extra durability which is added to the fabric which is ideal for camping as it will increase the life of your liner.

There are also other materials such as cotton, wool and fleece which will be able to give you that layer of warmth that you could be looking for. These are naturally the heavier and bulkier of the material types and they will also absorb a lot of water when they are wet and won’t dry quickly but could be the best material if you’re going to be camping somewhere cold.


When it comes to these bag liners there are generally who types that you can buy and that will either be the rectangular type which is meant to fill the inside of a normal sleeping bag but there is also the option of having a mummy style liner too depending on your preference.

If you have a double sleeping bag when it would make sense to get the regular sleeping bag which will be able to cover the whole of the bag. This will mean that you can share body warmth and actually use the sleeping bag as it was meant to be used.

With these two types though, you are generally going to match yourself up to the sleeping bag that you have. If you have a mummy sleeping then you’ll need to get a mummy liner as otherwise it wouldn’t fit. It could be though that you like the idea of the mummy liner and want to sleep in one in a regular bag.

This really comes down to personal preference but you also need to take a common sense approach to ensure that you won’t be left frustrated by getting the wrong type of liner for your sleeping bag and not being able to have that comfortable sleep.


The fit of a liner is important for two reasons. Firstly, you want to be able to match the size of the sleeping bag that you’re sleeping in. Secondly, you want to ensure that you are getting a sleeping bag that is going to be able to match your height.

If you’re tall then you want to make sure that you’re not going to have problems. It would be very frustrating to get a liner which is unable to cover the whole of your body as that goes against everything that it was designed for. Checking the product length is important before you buy any liner.

It could be that you don’t mind sleeping in a smaller space than your sleeping bag in you want a cozy liner and that would be up to you but what you don’t want is a liner which is far bigger than your sleeping bag, as not only would this be a waste of size and weight but it would also be frustrating with the liner folding in on itself.


Climate is a critical part of buying a liner, not only in the aspect of making sure that you’re not too cold but also in the aspect of ensuring that you’re not too warm either, as both can apply depending on your location.

If you are looking at getting a liner for cleanliness and comfort but will be sleeping in a warm climate, then this could be too warm. Equally if you’re getting a thin sleeping liner for a thin sleeping bag then you might be too cold.

You need to check your climate and make sure that both your sleeping bag and your liner are going to be a great match for it. It might be the best idea to get a comfortable liner which you would be able to sleep in outside of a bag when it’s warm and inside of it when it’s cold.


There are a few different ways in which your liner is to give you a layer of protection. The first is the protection that it will give from your sleeping bag. Sleeping bags are very hard to clean but liners aren’t which means that they can absorb the sweat and dirt from your camping trip and be easily washed, protecting your sleeping bag.

The other protection that some of them are able to give is from bugs as some of them have a layer of insect repellent in them which will be able to keep them away. This though will generally only last for a certain amount of time and wouldn’t really be required if you’re sleeping in a secure tent.


If you’re sleeping in a bag and a liner, then it could get very hot in there, whilst you want that body heat to be able to give you a level of insulation, you wouldn’t want a very humid bag which is going to make you sweat too much.

Some people sweat a lot more than others, so if you’re prone to sweating then this becomes even more important. You want to look for materials which are going to be able to wick away any moisture to the outside of the liner so it can then be evaporated away easily.



Q: What Is A Liner For Sleeping Bags?


A liner for sleeping bags can be seen in many respects in the same way as your duvet cover and bed sheets are at home. They are able to give a layer of protection to increase your comfort and also save you from having to clean items that are very hard to clean, such as a duvet or sleeping bag.

They dramatically increase hygiene but they will also increase your comfort levels too, giving you a more peaceful night’s sleep. The extra quality of liners is to give you an extra layer of insulation so you are able to stay warmer for longer.

There are also the other uses that come with it too. In warmer climates, it can be used as a sleeping bag in its own right and larger ones can even be used as a bedsheet at home. Also if you’re cold, they can double up as a liner.

Q: How Do I Clean A Sleeping Bag Liner?


Perhaps the biggest appeal of sleeping bag liners is that the overwhelming majority of them are machine washable meaning that you can come back from your trip, throw it in the washing machine and not have to worry about cleaning your sleeping bag as often.

It’s important to always check the instructions though to make sure that it is machine washable but more frequently, to check for any advice, as often they have delicate materials which require a different kind of wash to other clothes.
