Important Features to consider Before Buying

If you are looking to buy a sleeping bag liner then you need to know more about a few features that make one different than the other one. We will help you by explaining all the necessary features that are needed for a great sleeping bag liner. To make it easier for you, we are going to elaborate each one separately.

Material

It is quite obvious that material is one of the most important features when you are considering purchasing a sleeping bag liner. If you are looking for a more natural feeling, then you have to choose a proper material that will feel natural to your skin like cotton or silk.

On the other hand, if you are looking for a liner that will be durable and offer great insulation, then a synthetic material liner is what you should be considering.

Both of these types of materials are great in their own way and you won’t make a mistake with either, so there is one less thing to worry about.  If you are an environmentally friendly person then you will go for a more natural material.

At the same time, if you like getting the job done easier, you will choose synthetic materials. It all depends on your personal needs.

Temperature

Lower temperatures shouldn’t stop you from spending some time away from that urban jungle. Besides keeping your sleeping bag  clean and adding extra comfort, sleeping bag liners can act as great insulators.

For example, if the temperature is too low, a good, thick liner will add a layer of insulation and help you keep that warm air trapped close to you.

Also, if the temperatures are high, then, depending on the chosen material, the liner can act as an added layer of insulation from the heat. Meaning that it will stop the hot air from the outside, from entering your sleeping bag.

So, it all comes down to the season you plan to use the liner in. If it’s for winter, then natural, thick materials that are not breathable, will do the job, while the synthetic ones will keep you from getting overheated during the summer.

Size

This is an obvious feature that you should consider before hitting that order button. However, many people tend to forget to check if the size of the liner fits their sleeping bag and end up with a liner that is either too big, which is not that much of a problem, or with a liner that is too small, which makes it practically useless for the intended purpose.

Therefore, before buying a sleeping bag liner, make sure that its size matches the size of your sleeping bag. Ideally, it should be just a little bigger than the bag so that after washing, in case it shrinks, it doesn’t become too small to fit your sleeping bag.

Shape

Another obvious thing, yet people either don’t think about it, or they simply forget that just like sleeping bags, the liners have specific shapes as well. For example, if you have a classic, rectangular shaped sleeping bag, a mummy shaped liner would be of no use to you.

Image showing the Big-Agnes-Lost-Ranger-Sleeping-Bag

That is why you need to pay attention to the shape of the sleeping liner. As you might have guessed already, it needs to match the shape of your sleeping bag. So, if you have a mummy shaped sleeping bag, a rectangular liner is not for you, but a mummy shaped one.

Waterproofing

If you are using your sleeping bag in dry conditions, than any type of liner material will do just fine. However, in case your camping trip includes areas that are known to be rainy or accumulate plenty of damp during the night and especially in the morning, then what you need is a liner that is fully waterproof.

This way, not only that you will keep your sleeping bag from getting all stained up, but you will also keep yourself warm and dry no matter the weather conditions. But, keep in mind that waterproofed liners usually don’t have good breathability capabilities, so they are not that good for hot weather areas.

    I’ve tried many different sleeping bag liners and nothing has topped silk for me yet. It’s ridiculously soft and comfortable, usually easy to wash if you have the right blend, and sometimes surprisingly affordable. The Cocoon Silk Mummy liner is my all-time favorite liner, and their color selection is impressive.

    • John C. Porter

      It definitely is quite nice.

  • Oscar Wade

    For a person whose work entails travelling much, I sleep in different places and one time, circumstances forced me to sleep in a tent for a few months. I looked for a sleeping bag online and someone highly recommended the Cocoon Silk. Every time I use this sleeping bag, I am glad that I took his advice because other that being warm and comfortable, it feels quite beautiful to sleep in.

    • John C. Porter

      Thanks for telling us!

  • Robert Smith

    I am considering buying the TETON Sports 179-P, one reason being that it has a warranty. I never bought one before so I do not have an exact preference. I have a very expensive sleeping bag that I am so attached to and I would like to keep it in good condition for the longest time possible. I think the sleeping bag liner is ideal since it is easily dried and machine washable so I can always sleep in a clean sleeping bag.

    • John C. Porter

      We love it!
