Guide to Choosing the Best Sleeping Bag Liners

At first glance, it may seem like all sleeping bag liners are very similar as they have the same purpose. However, there are some key differences between them making some a better choice than others. This guide will help you to find the best sleeping bag liners for you.

Materials and Types of Sleeping Bag Liners

The materials used in a sleeping bag liner can make a big difference to its effectiveness and to the price. The four most common types of sleeping bag liners are silk, synthetics, thermal, and microfiber. Here are the benefits of each:

  • Silk sleeping bag liners- Although silk is the most expensive option, it has many benefits. It has excellent insulating properties and is soft against the skin. It is also high wicking, lightweight, and can protect against insect bites.
  • Synthetic liners- Synthetics are cheap materials that are breathable and lightweight. They are also soft to the touch and machine washable.
  • Thermal/ insulated sleeping bag liners- A thermal sleeping bag liner is the warmest option and they allow you to use a thinner sleeping bag, even in cold weather. They are breathable, allow for easy movement, are soft to the touch, and are machine washable.
  • Fleece/ microfiber sleeping bag liners- Microfiber is one of the cheaper options, but it provides a good level of warmth and you can use it on its own in good weather. They are also lightweight and machine washable.

Sleeping Bag Liner Shapes

There are two main sleeping bag shapes; mummy and regular. It is important that you buy a sleeping bag liner that is the same shape as your sleeping bag. This means it will fit well, feel comfortable and keep all parts of you warm.

  • Mummy-shaped liners-These are wider at the shoulders and tapered towards the feet. They give a more snug fit for keeping you warm in the winter.
  • Regular sleeping bag liners- These will fit in any sleeping bag that is not mummy-shaped. The advantage of this shape is that you can use it as a standalone sheet in warmer months.


Most people buy a sleeping bag liner to keep them warm, so the level of insulation provided is a key factor when making your choice. The two best options in terms of insulation are microfiber/ fleece or insulated sleeping bag liners.

  • Fleece sleeping bag liners- In most instances, a fleece sleeping bag liner will increase the temperature in a sleeping bag by 12 degrees Fahrenheit.
  • Insulated sleeping bag liners- These thermal sleeping bag liners are often made from a material called Thermolite®. They claim that they can increase the temperature in your sleeping bag by as much as 25 degrees Fahrenheit. A Thermolite sleeping bag liner is more expensive than the fleece option.

Other Considerations

  • Price- These are a relatively affordable piece of equipment for outdoor pursuits enthusiasts, although prices may vary. The price depends on the brand, the shape, and the materials used.
  • Insect protection- If you are planning to travel to areas known for bug infestations, then choosing a sleeping bag liner that has built-in bug-protection is wise.

What is a Sleeping Bag Liner?

Sleeping bag liners are a layer of fabric that you insert into your sleeping bag. They are made from different materials and come in different thicknesses, so they are suitable for several purposes.

What Are the Benefits of a Sleeping Bag Liner?

The main purpose of a sleeping bag liner is to increase the warmth in your sleeping bag, thus making you feel more comfortable. However, this is not the only way in which you can use a sleeping bag liner. These are versatile items that people spending the night outdoors or in a tent use in a variety of ways and they have several benefits.

Hygiene- A sleeping bag liner adds a layer of protection between you and your sleeping bag. This reduces the amount of sweat and dirt that get on the inside of the bag. This is useful as sleeping bags are bulky and tricky to wash. It is much easier to wash a liner.

Standalone sheet- Some people use these as a standalone sheet and not as a liner for a sleeping bag. For example, those who want to sleep directly under the stars in the summer months may use them for outdoor sleeping and ultralight backpackers may use them as an alternative to a sleeping bag.

Insect bite protection- Another benefit of having a sleeping bag liner is they can reduce the likelihood of getting bitten by an insect as they give an extra layer of protection.

However, it is important to note that if you are sleeping in freezing conditions, you will only feel warmer and this does not necessarily mean you will feel warm.

Even the best sleeping bag liners can only improve your sleeping conditions and not completely resolve the impact that freezing conditions will have on your comfort.
