Best Sleeping Bag Liner Buying Guide

There are many factors that you will need to consider before selecting your sleeping bag liner.

If this is an investment that is going to be subject to frequent use, then of course it has to be durably designed and comfortable too.

Below, we have identified many features of sleeping bag liners and our top tips for choosing the best product for your needs. 

The Type of Material

The market offers multiple choices in regards to the type of sleeping bag liners that are available.

The most common materials used are silk, cotton, fleece, or synthetic materials. Each can be beneficial in their own ways. 

Silk is lightweight for convenient portability and is considered to be the most bugproof. 

Cotton is strong and absorbent for enhanced durability. 

A fleece liner is going to be thicker providing a greater layer of insulation which is going to be appreciated on colder nights. 

Synthetic liners tend to be the most breathable making them a valuable addition to warmer locations as they are going to absorb the moisture from your body. 

The Size

It is important to consider the size of your sleeping bag liner before making your purchase.

If you are taller you will want to select a longer liner that offers you sufficient room that allows you to move around freely.

For those that are shorter, having excess room isn't likely to be a huge cause for concern.

Choosing a liner that is compatible with your height is important in allowing you to attain a comfortable night's sleep.  

The Shape

There are two different shaped sleeping bag liners available. The type that you choose is of course going to depend on the shape of your sleeping bag as this will determine which is more compatible.

It will also depend on your comfort preferences when it comes to sleeping inside your liner. A mummy-shaped liner tends to be more fitting, similar to a mummy shaped sleeping bag.

This type of liner also helps to prevent body oils or dirt from entering your sleeping bag. Likewise, a rectangle-shaped liner is compatible with rectangular sleeping bags and is less fitting to your body.


A sleeping liner is likely to be accompanying you on your camping tramps and for this reason, ideally, it should be lightweight and easy to transport.

Those that can be folded down are going to be a much more convenient addition to your luggage.

The material of your liner is also going to affect how easy it is to transport as some are going to be bulkier than others.

A liner that comes with a handy storage sack is preferable as this provides you with a place for storing your liner in between uses, making it much easier to transport in between locations. 

The Durability

The durability of your sleeping bag liner is also important, particularly if you are a frequent camper. Although your liner is going to be layered inside your sleeping bag it is still at risk of becoming damaged.

As you get in and out of your liner there is a risk of weaker materials tearing. There is also a risk of oils and other products transferring from your body onto the liner material.

Your liner should be durably designed from materials that can withstand the conditions of the outdoor environment without deteriorating in quality at a fast pace. 

The Insulation

A sleeping bag liner also provides you with an additional layer of warmth.

If you are camping in colder climates where you are sleeping directly on the ground you are exposed to the harsher temperatures. 

A sleeping bag liner acts as an additional layer of insulation helping to maintain the warmth.

Bug Repellent

Certain types of sleeping bag liners are known for possessing bug repellent qualities.

Warm climates are likely to attract more bugs to your sleeping area.

For many, this is likely to be a concern that can disrupt your sleep. If this is the case, it is important to select a liner that is made using bug repellent materials.

The Cost

Most sleeping bag liners tend to be pretty affordable with the majority retailing within a lower price range, others may seem pretty heftily priced.

When it comes to a sleeping bag liner the quality can often be reflected in the retail price. Choosing a cheaply priced liner may mean that the materials are of poorer quality and are likely to become easily damaged as a result.

Those that retail at slightly higher prices are likely to be made using better quality materials and are therefore less likely to become easily damaged. We have included a variety in our guide to highlight the variety that is available to you.
