Sleeping bag liners offer a practical solution to keeping sleeping bags clean and hygienic when camping or backpacking.
Sleeping Bag Liners
Whether camping, hiking or bike touring, if you look after your kit then your kit will look after you. Sleeping bag liners fall neatly into this category, protecting your sleeping bag and thus enabling it to last longer.
Sleeping bag liners are lightweight, protective layers designed to be inserted inside a sleeping bag. They serve as a barrier between the sleeper and the sleeping bag itself, offering multiple benefits which vary based on the liner's material and design.
The primary purpose of sleeping bag liners is to enhance the comfort and functionality of sleeping bags. They provide hygiene, additional warmth, and versatility. Moreover, they can prolong the life of the sleeping bag by protecting it from wear and tear.

Why I Use Sleeping Bag Liners For Travel
Most of the travel I do which needs a sleeping bag is to do with camping when bicycle touring. When you have to carry everything on your bike, you have to think hard about what items to take, but one item that never gets left behind is my sleeping bag liner.
I’ve currently got a relatively cheap silk sleeping bag liner from Decathlon, but there are plenty of other types to choose from.
Fleece Liners
Fleece liners are known for their exceptional warmth. They are ideal for colder environments, adding significant insulation to a sleeping bag.
Silk Liners
Silk liners are lightweight, compact, and offer a smooth, luxurious feel. They are perfect for adding a bit of warmth and enhancing the sleeping bag's comfort without much additional bulk.
Cotton Liners
Cotton liners are popular for their affordability and comfort. They are breathable and ideal for use in moderate climates. However, they can be bulkier and heavier compared to silk or fleece options.
Advantages of Using Sleeping Bag Liners
Bag liners are a versatile piece of travel gear, but often overlooked even by experienced travellers. Their primary function, is to act as a separate layer between you and your sleeping bag.
This way, the inside of your sleeping bag will stay clean and odour free. It is also a lot easier to wash and dry a sleeping bag liner as your travel, than the sleeping bag itself.
Their secondary functions include acting as a thin sheet when the temperature is too warm for a full sleeping bag, and to sleep in when staying in hostels or cheap hotels.
If you have ever stayed in a cheap hotel or hostel, you will know just how questionable some beds and mattresses are when it comes to cleanliness!
The sleeping bag liner acts as a protective cocoon, and you can simply wash it before you leave. Check out the video below of a cheap hotel room – I definitely needed my sleeping bag liner here!
Reasons to use sleeping bag liners

‘[They] can keep you separated from beds and mattresses of dubious quality’ – You sold it to me right here!!
A very useful item indeed! I’ve had a silk one for ages – a rectangular one, which offers more leg space. I always carry it, along with a travel towel, when I need to save space and weight.
I agree – A sleeping bag liner really is a useful piece of travel gear.
