Sleeping bag liners are a handy addition to your camping gear, providing a little extra warmth on cold nights and keeping your sleeping bag clean. They come in various materials, including silk, fleece, and cotton, and can add between 5 to 15 degrees Fahrenheit of warmth to your sleeping bag, depending on the liner material and thickness. While some claim that insulated liners can add up to 25 degrees Fahrenheit of warmth, others argue that the primary purpose of a liner is cleanliness rather than added warmth. Liners can also add extra weight to your pack, so it's important to consider the trade-off between warmth and weight when choosing whether to bring one along.

What You'll Learn
Silk liners add around 5°C
Sleeping bag liners are a handy item for backpackers and travellers. They are available in two main types: mummy-shaped liners designed to slip inside your sleeping bag, and rectangular liners (also known as travel sheets) designed for use on their own or inside a rectangular sleeping bag.
Liners are typically made from silk, fleece, or cotton. Silk liners are lightweight and ideal for most thru-hikes. They offer a little extra warmth and are very breathable, making them suitable for both cold and warm weather. Silk liners are also compact and easy to pack, weighing in at about 5 oz.
Silk sleeping bag liners can provide around 5°C of extra warmth. This makes them a good option for cold sleepers, or for use in slightly colder temperatures. However, it's worth noting that some people have reported that they did not notice any difference in warmth when using a silk liner.
In addition to providing warmth, silk liners can also help keep your sleeping bag clean, as they can be more easily laundered than a sleeping bag. This makes them a good choice for travellers who may be sleeping in bedding of questionable cleanliness.

Insulated liners add up to 25°F
Sleeping bag liners are a handy item to have, especially for backpackers and travellers. They are useful for keeping your sleeping bag clean and can provide some extra warmth on cold nights. The amount of warmth they offer depends on the thickness of the liner and the material it is made of.
Insulated liners, for example, can add up to 25°F of warmth to your sleeping bag. This is a significant increase in warmth and can be a great option if you are camping or backpacking in colder climates. Insulated liners use hollow-core fibre insulation, which helps them dry 50% faster than cotton. This type of liner is typically moderately to expensively priced.
The weight of your sleeping bag liner is an important consideration, especially if you are backpacking and need to carry your gear for long distances. Silk liners are lightweight and ideal for most thru-hikes, providing a little extra warmth. Cotton liners are mid-weight and ideal for travel, but they offer no warmth when wet, so they are not suitable for backpacking. Fleece liners are heavier and much warmer, making them a good option if you encounter very cold temperatures. However, they also add a lot of weight to your pack.
While some sources claim that sleeping bag liners do not add noticeable warmth, the general consensus is that they provide a few extra degrees of warmth, which can make a difference in cold conditions. It is worth noting that the degree of warmth provided may depend on the individual, as people have different tolerances to cold. Additionally, the accuracy of sleeping bag ratings has been questioned, and it may be more efficient to prioritise clothing that will keep you warm.

Fleece liners add warmth but bulk too
Sleeping bag liners are a great way to add extra warmth on cold nights. They are also useful for keeping your sleeping bag clean and are particularly helpful for travellers staying in hostels or hotels.
Liners come in three main types of material: silk, fleece, and cotton. Silk liners are lightweight and provide a small amount of extra warmth, while cotton liners are mid-weight and ideal for travel as they offer no warmth when wet.
Fleece liners, on the other hand, are heavier and provide a significant amount of warmth. They are perfect for encountering very cold temperatures, especially if you only have a lightweight sleeping bag. However, they can add a lot of bulk to your pack, sometimes as much as carrying another sleeping bag. This bulk can be undesirable, especially for backpackers who are already carrying a lot of gear.
If you're looking for a warm liner that won't add too much bulk, the Sea to Summit Thermolite Reactor Fleece Liner is a popular choice. It provides significant warmth without the weight or bulk typically associated with fleece materials. The Thermolite Reactor Fleece Liner weighs only 13.4ozs / 379g and can add up to 14°F of warmth to your sleeping bag. It can also be used as a standalone sleeping bag in temperatures down to around 50°F / 10°C.
So, while fleece liners do add warmth, they can also add bulk. If you're looking for a warmer option without the bulk, the Thermolite Reactor Fleece Liner could be a good choice.

Mummy-shaped liners fit inside sleeping bags
Mummy-shaped sleeping bag liners are designed to slip inside your sleeping bag. They are particularly useful for backpackers and travellers who sleep in hostels. They can add an extra layer of insulation, warmth, and comfort, as well as protecting your sleeping bag from dirt, body oils, and bacteria. This is beneficial because it is much easier to launder a liner than a sleeping bag, and it will help extend the life of your sleeping bag.
Sleeping bag liners are made from a variety of materials, including silk, fleece, cotton, synthetic materials, and insulated materials. The material you choose will depend on your specific needs and preferences. Silk liners, for example, are lightweight and ideal for most thru-hikes, while fleece liners are heavier and better suited for colder temperatures. Synthetic materials like CoolMax® are moisture-wicking and breathable, making them suitable for humid conditions. Insulated materials like Thermolite® can add significant warmth to your sleeping bag, with some claiming to add up to 25°F. Mummy-shaped liners made from this material can be a great option if you're looking for extra warmth.
The amount of warmth a sleeping bag liner adds can vary depending on the material and thickness of the liner. Liners made from materials like fleece and insulated fabrics will generally provide more warmth than silk or cotton liners. Some sources claim that a liner can add anywhere from 5° to 15°F of extra warmth, while others state that a silk liner can add around 5°F. Insulated liners are claimed to add up to 25°F of warmth. Mummy-shaped liners made from insulated materials can be an excellent choice if you're looking for a significant increase in warmth.
It's important to note that the effectiveness of a liner in adding warmth also depends on the quality and accuracy of your sleeping bag's temperature rating. Higher-end bags tend to have more accurate ratings, while lower-end bags may be inaccurately rated, requiring you to add more layers or choose a lower temperature rating to achieve the desired warmth. Additionally, individual factors, such as gender and metabolism, can also influence how warm or cold you feel when sleeping.
Mummy-shaped sleeping bag liners offer a versatile option for those seeking extra warmth, cleanliness, and protection for their sleeping bags. They can be used in various environments and are easy to pack and transport. When choosing a liner, consider the specific features you require, such as moisture-wicking, breathability, or added insulation, to ensure you select the best option for your needs.

Rectangular liners can be used on their own
Rectangular sleeping bag liners, also known as travel sheets, can be used independently or inside a rectangular sleeping bag. They are ideal for travellers who want to avoid questionable bedding and are often recommended, and even required, for use in hostels and budget hotels. Rectangular liners are also a good option for car camping in warm weather, saving space in your car for other gear.
Rectangular liners can be made from silk, cotton, or synthetic materials. Silk liners are lightweight and ideal for most hikes, providing a little extra warmth and cleanliness. Cotton liners are durable, heavy, and absorbent, making them economical for hostel accommodations, but they are not recommended for the trail due to their weight and slow drying time. Synthetic liners, such as those made with CoolMax®, are moisture-wicking and breathable, making them suitable for humid conditions and restless sleepers.
The amount of warmth provided by a rectangular liner depends on its material and thickness. Silk liners can add around 5° to 15°F of warmth, while insulated liners made with Thermolite® can add up to 25°F. However, some sources claim that sleeping bag liners do not add significant warmth, and the extra weight may be better invested in clothing.
In addition to warmth and cleanliness, rectangular liners offer versatility. They can be used as a mattress cover or a camping blanket, and in hot climates, they can be used without a sleeping bag. Ultimately, the decision to use a rectangular liner independently or with a sleeping bag depends on personal preferences and specific needs.
