Sleeping bag liners may not be the sexiest of pieces of kit, but they provide a vital function in both colder and warmer climes. Many experienced backpackers simply wouldn’t dream of traveling without one.
In colder destinations, a good sleeping bag liner is worth its (very little) weight in gold, adding an extra layer of warmth to a sleeping bag or the blankets of a bed. In tropical locations, they provide a lightweight travel sheet that will see you through a good night whether in a hostel, on a train, or even camping in the jungle.
Convinced? Great! Ordinarily, you’d now have the task of searching the outdoor stores for the sleeping bag liner of your dreams. But not today, because we’ve done all the hard work for you! Keep reading to discover the best sleeping bag liners of today!

Best liner for mummy sleeping bags
Many sleeping bags on the market today belong to the mummy-style format, with narrower footing and elasticated lower panel intended to come right over the user’s head. These specific features mean you need a sleeping bag liner with a shape to match, and the Mountain Warehouse Microfibre Mummy Sleeping Bag Liner is one of the best. This sleeping bag liner is made from polyester rather than silk, meaning it remains clean and hygienic even over longer camping and backpacking trips while still being incredibly easy to wash on a standard washing machine cycle.

How to choose the best sleeping bag liner
Though at its most basic a sleeping bag liner is little more than a tube of material sealed at one end, like most products, there are a number of features and factors can elevate this into something more. So to choose the best sleeping bag liner for you, you need to ask yourself a few simple questions.
Firstly, are you looking for a sleeping bag liner that will see you through several seasons of tough camping – as an inner for a sleeping bag, or as a way of keeping the chill off during the short hours of sleep at a music festival? This will help you understand what you’re looking for out of a sleeping bag liner, and also how much you’re probably willing to spend.
It’s also a good idea to think about the time of year you’re going to predominantly use the sleeping bag liner. If the answer is winter, you’re going to benefit from buying a sleeping bag liner that can add a few degrees to the ambient temperature. If, by contrast, its for summer use – and somewhere hot or tropical – you’re going to want a sleeping bag liner that keeps you cool. The material the sleeping bag liner is made from – silk, cotton, or synthetic – will have a large part to play in this, as well as the overall weight of the liner if that’s an important consideration too.
Check out our rundown of the best winter sleeping bags here.
And if you’re buying a sleeping bag liner to slip inside a sleeping bag, make sure you buy the right type. This means identifying whether you have a mummy sleeping bag or traditional rectangular style!
