When it comes to camping, sleeping bag liners are a vital piece of equipment by acting as a barrier between you and your sleeping bag. The best sleeping bag liner not only provides you with an extra level of comfort but also allows your bag to stay cleaner for longer periods.

Choosing a sleeping bag liner involves taking a few key areas into accounts, such as temperature rating, material, fit, and breathability. Thankfully, we’ve already compiled a list of the best sleeping bag liners on the market after reading several sleeping bag liner reviews. Once you’ve read through this guide, you’ll know exactly what you need.

Many people think a sleeping bag liner is just about adding extra warmth. News flash; it isn’t! A sleeping bag liner can prolong the life of your sleeping bag by reducing contact between your moist skin and the inside of the bag. It improves hygiene because a liner is much more easily washable than an entire sleeping bag. A liner can even act as a sleeping bag all on its own for those really warm nights when you don’t want to wake up in a sweaty mess!

Of course, sleeping bag liners can be used to increase warmth when you don’t want to carry the extra bulk of a colder-rated sleeping bag. Throwing the small bag of a thermal sleeping bag liner into your pack along side your 3-season sleeping bag can be more convenient than packing a larger 4-season bag when the temperature is between the given comfort ratings of the two bags.

Bear in mind that a sleeping bag liner can become something of a straight jacket if you are someone who moves around a lot in your sleep. Certainly take into account the extra time it is going to take to extricate yourself from a tangled liner if you start to hear the call of nature for example - you don’t want to find yourself tied up when you need to be making a break for the facilities!

How To Choose A Sleeping Bag Liner – Buying Guide



Weight and comfort have a tricky relationship when it comes to camping gear. If you want your sleeping bag to serve more than a protective layer, it will be heavier as it would require more insulation material. Thin liners for sleeping bags will be lighter and easy to carry.


The most common material is polyester, as it is relatively inexpensive and lightweight. Silk, on the other hand, feels soft on the skin. There are also plenty of liners made with synthetic materials. Materials such as cotton, wool, and fleece are naturally heavier and bulkier. However, they are the best materials for colder climates if you won’t be moving around a lot.


When it comes to these sleeping bag liners there are generally two types: rectangular and mummy. If you have a double sleeping bag, it makes sense to get a regular sleeping bag that will be able to cover the whole bag, which means you can share body warmth and use the sleeping bag as it is meant to be. If you have a mummy sleeping bag then you’ll need to get a mummy-shaped liner, otherwise, it won’t fit.


When it comes to fit, you have to match both the size and the height of your sleeping bag. It would be very frustrating to get a liner that is unable to cover your whole body. A sleeping liner bigger than your sleeping bag, on the other hand, will not only be a waste of size and weight but also be frustrating with the liner folding in on itself.


If you are 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 get too cold. It might be the best idea to get a comfortable liner in which you will be able to sleep outside of your sleeping bag when it’s warm and inside of it when it’s cold.


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. Some sleeping bag liners protect against bugs as they come with a layer of insect repellent in them. 


If you’re sleeping in a bag and a liner, it could get very hot. Whilst you want that body heat to give you a level of insulation, you don’t want a very humid bag that will make you sweat too much. Look for materials that wick away any moisture to the outside of the liner so that it can be evaporated away easily.



Q: What is the best material for a sleeping bag liner?


Silk sleeping bag liners are the most user-friendly items as they grant ease and comfort by being lightweight. Additionally, silk liners for sleeping bags can be compressed and packed easily. With silk sleeping bag liners, you don’t have to worry about them staying wet after heavy rainfall as they dry up instantly. They are also antimicrobial.

Q: Can you sleep in a sleeping bag liner?


The answer depends on a few factors. The most important things to consider are the duration of usage and the temperature of the site that you are planning to use it in.

A sleeping bag liner is designed to be used as an extra layer of added warmth in the sleeping bag. On its own, you can use it to lie down on, but sleeping in it is not recommended. The reason is that sleeping liners are lighter when compared to sleeping bags. Thus, the cold air and breeze can easily pass through them unless you are sleeping in a tent or camping shelter.

Q: What is the point of a sleeping bag liner?


By adding sleeping bag liners, you get the benefit of feeling extra warm and also protect the quality of your sleeping bag from dirt and sweat. While it also safeguards you from insects and bugs, for some users, the sleeping liner itself functions as a sleeping bag in warm climates.

Q: Do silk sleeping bag liners protect you from bugs?


Yes, a silk sleeping liner acts as a layer of protection and functions as an extra barrier by stopping certain types of bugs and insects from reaching you by functioning as an insect shield.

Q: How to attach a sleeping bag liner?


Start by turning your sleeping bag inside out and put the liner on top of it. Attach the zipper of the liner, with the zipper of the sleeping bag and zip it up. If it has any Velcro tabs, then secure them tightly. Lastly, get in and tighten any openings with the help of given straps and close them off to be safe from cold air.
