A sleeping bag is essential for camping. It forms the basis for the sleep system you build for a comfortable night of slumber. A sleeping bag liner enhances your sleeping bag and it is a very worthy purchase, as these little additions to your outdoor kit are often overlooked. If you camp in icy temperatures, a sleeping bag liner for cold weather is surely going to be useful for you.
These sleeping bag liners add warmth to your sleeping bag as well as home-style comfort. They also make your sleeping choices more versatile, since during warm nights you could use the liner by itself. A liner works by acting as an inner layer to your sleeping bag. It is usually made of a thin cloth and is intended to be a barrier between you and the actual sleeping bag itself.

Advantages and Features of a Sleeping Bag Liner for Cold Weather
A sleeping bag liner is not only beneficial for warmth in cold weather, as it is also terrific for warm weather. Rather than pack your hefty and bulky sleeping bag around that will be too hot and overkill, you might just need your liner. They are very light and the majority of them can pack down enough to fit inside a small backpack pocket.
If you happen to be camping in summer when nighttime temperatures are a bit too hot for your sleeping bag but a tad too cool for sleeping in the open air, a sleeping bag liner can give you that exact warmth and comfort needed to get in some nice slumber in the outdoors.
Conversely and depending on the thickness, a sleeping liner can provide added insulation and a lot of extra precious warmth inside your sleeping bag. For instance, a sleeping bag rated at 35 degrees, with the addition of a 10-degree liner, could then be rated at 25 degrees.
Washability of Sleeping Bag Liner For Cold Weather
Sleeping bags are cumbersome to wash. Taking them to the dry cleaners is also expensive and time-consuming. Besides, some cleaners might not know how to treat a sleeping bag and can damage it’s loft and insulation qualities. In contrast, sleeping bag liners are easily washable at home and save you effort and money.
Still more on the cleanliness subject, by using a liner for sleeping, you will inevitably minimize the amount of dirt, grime, and other filth that you bring into your sleeping bag. Protecting a $600 bag with a $45 liner makes a lot of common and financial sense.
Let us be honest. Outdoors enthusiasts can sometimes be lax on hygiene habits. It is not really our fault since one’s bathing choices are far from ideal when out in the wild. As a result, even if we are finicky about bodily cleanliness when in the outdoors, sleeping bags tend to attract and collect odor. Liners mitigate that issue by offering a washable “layer’. This extends the life of your sleeping bag by minimizing the washing, thus protecting the materials.
The majority of backpacking fabric is synthetic. Most sleeping bag material is synthetic and many hikers yearn for the feel of bed sheets at the end of a long hike. A soft sleeping bag liner to snuggle up inside is the next best thing when you are camping.
Qualities To Consider In A Sleeping Bag Liner For Cold Weather
Apparently, a 30-degree thermal liner will be heavier than a 10-degree sheet. Think and weigh how much of a priority the thermal properties are to you before buying a heavy liner. Even the heftiest liners should not weigh more than a pound.
Should I get a tapered or rectangular liner? You can get liners that are rectangular in shape that are more spacious to sleep in. You could also opt for tapered around the head and feet, which will pack lighter and more compact. Some models are also made with an adjustable drawstring around the top to tighten it around your head.
This has to do with the ease of maintenance. Silk fabric liners are usually easy in terms of quality and compact size. To keep them in good condition you will have to hand wash them. Polycotton and microfiber liners, on the other hand, can all be washed in the machine along with the rest of your gear.
Having already spent a lot of money on your sleeping bag, you want to be sure to line it with a layer that will offer the best in terms of the performance to price ratio. If a liner is expensive, check that it is of premium quality and has the endorsement of satisfied customers in user reviews. Do the same if you find a very inexpensive liner. Try to investigate what it is missing that other liners have such as double stitching, antibacterial properties, a hood, and small compact size, for instance.
There are many kinds of liner materials like silk, cotton, fleece, merino wool, and polyester combinations that are the most used. Cotton is a favorite simply because of the way it feels on the skin. The downside is it is slightly heavier and useless when wet. Silk is very lightweight and ultra-comfortable, but less hard-wearing. Fleece is inexpensive and warm, but bulky and heavy. Merino wool is ideal providing lightweight, warmth, and comfort but carries a hefty price tag. Polyester blends range all over the market on materials.
The majority of companies will give some kind of temperature rating in the specifications. This number is the additional amount of warmth a liner can provide. The warmest backpacking liners are given a rating of up to 15-25 degrees.
All sleeping bags can get quite hot, hence you want a liner to help wick any moisture away from your body. Not a dealbreaker, but look for sleeping bag liners with a “CoolMax” trademarked feature if you have a tendency to perspire.
If you enjoy cowboy-style camping with no tent, a lot of critters and bugs active at night on and around you can be a nuisance. There are sleeping bag liners that come with insect-resistant coated fabrics to repel any unwanted nocturnal creatures.

[su_service title=”Sea To Summit Reactor Thermolite” icon=”icon: star” icon_color=”#2D3092″ size=”32″ class=””][/su_service]
The S2S Reactor Thermolite is a high quality sleeping bag liner for cold conditions that’s very compact and lightweight for it’s insulation capabilities.
This sleeping bag liner is said to elevate your sleeping bag’s temperature rating by up to 15 degrees Fahrenheit. A capability worth spending on and which makes it a real contender for the best-insulated sleeping bag liner in the market.
In addition to its stellar warmth-improving rating, the Reactor packs to a compact size. It is 3 x 5 inches, weighs a mere 9oz, and is 210cms long. Side by side against other high-end liners, the Reactor is able to keep up. It is also a good option for taller folks thanks to an extra 10cm from top to toe.
If you’re an ultralight camper, this sleeping bag liner is miles better compared to others because of it’s packability, weight, and compactness.
However, due to the ultrathin synthetic fabric that is used by the Reactor, it lacks a soft and cozy feeling that you’ll get from fleece or silk liners. This might be a problem if you’re a picky sleeper that can’t sleep in anything other than cozy liners.
All in all, the sea to summit reactor Thermolite is a great lightweight sleeping bag liner that’s perfect for ultralight campers. Due to it’s compactness, you can also store this as your EDC gear in your vehicle’s trunk.
[su_service title=”ALPS Mountaineering MicroFiber Mummy” icon=”icon: star” icon_color=”#2D3092″ size=”32″ class=””][/su_service]
ALPS MicroFiber Mummy has an ultra-cozy, comfortable feel. As far as price goes it is the middle ground between high-end silk options and budget models.
This liner is made out of brushed polyester and microfiber that’s quite soft. Because of that, it’s very cozy and comfortable to sleep in, especially when it’s cold outside. It also has a decent insulation that can give you around 5 – 10 degrees to your sleeping bag’s temperature rating.

It packs down to a very compact 3.5 x 6.5 inches and offers a slightly more generous layer than other ultra-thin liners. However, this sleeping bag liner is quite heavy. Because of that, ultralight campers should find other lighter sleeping bag liners for their cold weather camping needs.
All in all, this is a very good choice for those seeking a well-made mummy-style sleeping bag liner that offers great value for money.
[su_service title=”Rab Silk Ascent Sleeping Bag Liner” icon=”icon: star” icon_color=”#2D3092″ size=”32″ class=””][/su_service]

Spanning a length of 89 inches, this sleeping bag liner has a minimum of 5cm more length than any of its competitors out in the market.

For ultralight campers, the RAB ascent is a great choice because of it’s weight. You can carry this in your pack without worrying that it’ll weigh you down.
While this is a pricier option than most, the pillow insert and extra length make it arguably one of the best sleeping bag liners for backpacking. The only downside to the RAB Ascent is the price unless you think the size, weight, and comfort justifies it.
[su_service title=”Sea To Summit Premium Silk Travel Liner” icon=”icon: star” icon_color=”#2D3092″ size=”32″ class=””][/su_service]
Although the lofty price tag of the S2S Premium Silk Travel Liner could make you frown initially, a closer look at the details might just convince you that it is that good.

However, this liner is made of ripstop silk and is machine washable. This makes the silk liner more durable and easier to clean after being used. That fact along with the built-in hood makes this one of the best backpacking liners in the market.
