How to Choose Sleeping Bag Liners in the UK
- Choose a Suitable Material for the Season and Environment
- Ensure the Shape of the Liner Matches the Shape of Your Sleeping Bag
- Check the Liner’s Size and Weight
Consider the Material: Fleece Liners Are Great for Cold Weather, Cotton Is Breathable and Long-Lasting
- Silk: Breathable, insulating and extraordinarily lightweight, silk is all you can hope for in a sleeping bag liner. The only drawback is that it can be quite expensive compared to other materials.
- Cotton: A more economically viable option, cotton is strong and durable. It tends to last longer than most fabrics, surviving multiple washes before showing signs of wear. However, it is a little heavier and will take up more space than silk.
- Fleece and Microfleece: For the colder weather, a warmer option like fleece or microfleece can add as much as 11°C to your sleeping bag. It's reasonably priced and absorbent, but is one of the bulkiest and heaviest options you can buy.
- Synthetics: Fabrics such as polyester are moisture-wicking and breathable. For use in humid atmospheres, these fabrics are ideal and the stretch is perfect for manoeuvrability. So if you tend to toss and turn, this will be the best option for you.
- Insulated Fabrics: If warmth is your priority, insulated liners will be your best bet. They can range in price depending on the quality of the materials used, but adding an insulated liner to a light spring or summer bag can help you adapt your kit to any weather conditions.

Ensure the Shape of the Liner Matches the Shape of Your Sleeping Bag
- Mummy: Designed to protect standard sleeping bags from dirt and body oils, these are usually tapered towards the feet and have a space or a hood at the opposite end.
- Rectangular: These can be used in rectangular bags, but are also often used on their own as sheets to line bedding in hotels and hostels, providing a protective layer against contamination.

Check the Weight and Dimensions to Make Sure You Have the Best Fit That Will Be Easy to Transport
The final consideration is the size and weight of the bag. Checking the measurements is important to ensure a proper fit inside your sleeping bag. If it's too small, you risk losing space inside the bag. If it's too large, you'll end up with excess fabric that can tangle and disrupt sleep. That's why you should always opt for a liner around 1-3 cm smaller than the measurements of your sleeping bag.
The weight is also a key factor, since you'll be transporting the bag liner along with your other camping gear, often on foot. Choosing a lightweight bag will ensure you have the most comfortable experience while travelling to and from the camp spot. Ideally, your liner should weigh under 350 g, as anything larger will start to feel like a burden.

The lightest on our list, weighing just 110 g, it will be easy to travel with and folds down to a small size. most importantly, it manages to remain reasonably priced, especially considering all of these sought-after features!
Durable Cotton Polyester Blend That Will Last for Years to Come
Trespass is a well-respected brand, and their camping and outdoor gear is always top quality. This mummy bag liner is no exception, with its polyester-cotton material providing great insulation and durability.
It comes in adult and child sizes, and the moisture-wicking fabric will prevent overheating while protecting your back while you sleep. Make sure to store it inside the accompanying travel sac when not in use, for fuss-free transportation.
Budget-Friendly Line Perfect for Anyone Looking for a Bargain
If you're shopping on a budget, look no further than Quechua's polyester sleeping bag liner. It's the cheapest on our list, without sacrificing quality, and is breathable even in humid conditions.
We like that it's relatively lightweight. Better yet, the rectangular shape makes it versatile enough to use in sleeping bags or as a protective liner for bedding when visiting hotels and hostels.
Compact Liner That Rolls Down to 20 x 10 Centimetres
The material of the liner is soft and breathable, and it will dry much faster than denser fabrics. As well as protecting the sleeping bag, the sewn-in pillow compartment also allows you to protect your camping pillow and avoid annoying slips during the night.
Sea to Summit Reactor Insulated Sleeping Bag Liner
An Insulated Mummy Liner for Camping in Colder Weather
The insulation is thicker in the foot and torso sections, to combat leading areas of heat loss in the body. In warmer weather, it can even be used as a standalone bag, retaining essential heat, without getting too hot.
A 100% Silk Liner With Polyester-Lycra Panels for Flexibility
It's relatively expensive, so it won't be ideal if you're shopping on a budget. However, if you're prone to a lot of movement in your sleep, the added room may be worth the investment.
Rectangular Cotton Liner in 3 Different Sizes
When shopping for a cotton rectangular liner, there are other options on the market that are better value for money. That said, if you need one of a specific size, this will be the most likely to fit your specifications.
An 89% Merino Wool Blend to Tackle the Toughest Chills
This liner is insulated with 89% Merino wool for greater thermal insulation and comfort. An eco-friendlier choice, Forclaz has made a climate promise to harvest only the necessary materials for this liner, with a significantly reduced CO2 impact compared to standard production.
It's the most expensive on our list, so it won't be ideal for the casual summertime camper. Still, if you're committed to camping out in the toughest of temperatures, you can't get much better than this!
100% Cotton Liner for Comfort and Airflow
If you want cotton, this is the best value you'll get. It'll resist wear and tear for a long time, thanks to the durable material, and the rectangular shape is suitable for use alone or inside a sleeping bag.
It's the heaviest on our list at 490 g, so if you often hike with your gear or travel on foot, you might prefer a lighter option. For occasional trips and travel by car, however, the weight shouldn't be much of an issue.
Warm Fleece Liner That Can Be Used Alone During Spring and Summer
Unfortunately, the brand has not confirmed the exact weight of the liner, so it may not be suitable if you're packing light. Bearing in mind that fleece is the heaviest fabric option, it certainly won't be compact.
