If you’re in a rush and want to find out what the best sleeping bag liner is, we recommend the Litume All Season Sleeping Bag liner.
We all know that camping doesn’t usually provide the most ideal conditions for restful sleep. Nights can be chilly, even in the summer, and while sleeping bags do a good job at keeping us warm most of the time, they don’t always block the cold as much as we’d like. If you’re looking for a little something extra to keep you snug and cozy at night without breaking the bank on an expensive sleeping bag, we’ve got you covered. Let’s take a look at some of the best sleeping bag liners that will keep you warm and comfortable.
In this article, we’ll be reviewing the following liners:
- Sea to Summit Thermolite Liner
- Tough Outfitter Sleeping Bag Liner
- Redcamp Fleece Sleeping Bag Liner
- Litume All Season Sleeping Bag Liner
- Vumos Sleeping Bag Liner
What is it?
Sleeping bag liners do exactly what they sound like…they line your sleeping bag. Now, we aren’t talking about the actual lining of the sleeping bag itself. Liners are a separate item that you can buy for your sleeping bag for a number of purposes. You can think of it as bed sheets for your bag, except instead of having flat sheets, the liner will form a cocoon around you. Not only are they great for keeping you warm during the night, but they also improve the overall comfort level of your sleeping bag.
Liners are good all year, though the way that you use them will vary accordingly. In the winter, they make a great insulating layer to help you stay warm during the night. While you should have a sleeping bag that does a good enough job at keeping you from freezing, the liner will make sure you stay extra toasty. Something to remember is that these items are rated in degrees (for example, you may find a 14 degree liner). What this means is that when you use it, the liner allows you to sleep in temperatures 14 degrees colder than you otherwise could have. So if your sleeping bag is good down to 30 degrees, this particular product would allow you to stay comfortable down to 16 degrees.
In the summer, you can use the liner as a stand alone item. A lot of sleeping bags can get too steamy to sleep in on a hot, summer night, so liners allow you to ditch the bag without losing all protection.
This one is important because you generally don’t want to wash your sleeping bag. The water and motion of the machine can ruin the filler of your bag, so if you want it clean, you usually have to do it by hand. This is obviously a pain to do every time you go camping, so why not save yourself the hassle by keeping your bag clean in the first place?
Liners are great because when you slide into your “bed” at night, the only thing that’s getting dirty is what you’re in direct contact with (aka, the liner). Unlike sleeping bags, liners usually are machine washable, so you can save yourself the headache of hand washing your gear.
At the end of the day, your sleeping bag is the cozy little place where you want to enjoy some time off your feet and sleep. However, it’s rare to find a bag that isn’t made from synthetic material, and most outdoor clothing (if you sleep in it) is made from something similar. Nothing says “creature comfort” like the nice, manufactured texture of nylon, right?
There are some people who aren’t bothered by this, and are willing to leave the extra gear behind, if comfort was the only deciding factor. But for many of you, sleep is something that you’ll want to enjoy, and finding the right liner will help you do that.
Liners come in a wide variety of materials, including polyester, cotton, fleece, and many more. Some are lighter than others, some feel better on sensitive skin, others are better at keeping you warm. Each have their own pros and cons, though I tend to prefer cotton and wool, as long as you don’t get cotton wet and don’t mind the steep price of wool.
Sleeping Bag Liner Reviews
Weighing in at a meager 9 ounces, this Sea to Summit liner isn’t just light, it also packs down to a smaller size than some phones. It’s a great product if you’re looking for something to give you some extra warmth at night without taking up too much space in your pack.
The mummy shape allows it to easily slide into any type of sleeping bag. Though it’s worth noting that even if you don’t have a mummy bag, it will feel like you do, since the liner has the shape of one. While not as constricting as a mummy bag can be, if you don’t like that style, this liner might not be the best option for you.
– Very lightweight
– Folds up into a tiny package
– 14 degree rating
– Mummy shape
– It’s a bit expensive for the overall quality
– Doesn’t seem to keep you as warm as advertised
If you’re looking for a cheap option, Tough Outfitters liner might be the way for you to go. The downside with taking the more inexpensive product, though, is that it won’t keep you as warm as many others in this review. Rated as a 5-10 degree liner, it’ll definitely help, but won’t be enough for extreme conditions. This is something that I would suggest you only use in temperatures that hover around freezing or above, as anything below that will likely be too cold for you.
Another way you could use this liner is as its own sleeping bag if you’re planning on staying in a hostel or a friend’s couch. In those cases, warmth is less important than having a barrier against any germs or dirt that might exist in those places.
– Cost effective
– Spacious sleeping area
– Packs down to the size of a sandwich
– Lifetime warranty
– While it does provide some extra warmth, it isn’t very much
– Can be difficult to get in and out
The one and only liner on this list that’s made out of fleece, Redcamp’s product isn’t just attractive for its 20 degree rating, but also for the comfort this material is known for. Thick and breathable, you’ll be able to stay both warm and dry regardless of weather conditions.
While fleece is undeniably one of the most comfortable, warmest materials a liner can be made from, it does come at the expense of added weight. Thick and heavy, it weighs almost twice as much as its competitors. It might only be a one pound difference, but that can be enough to make or break it for a lot of campers.
– Warm and soft material
– Large size that’s good for couples
– Two liners can be zipped together to make a big blanket
– Two way zippers
– The zippers aren’t the best quality
About as large as an iPhone X when packed away, you won’t even know you’re carrying the Litume all season liner. For being so small and light, it adds a surprising 22 degrees to your sleeping bag, which should be more than enough to keep you warm in almost any circumstance.
Soft and elastic, you might not want to wake up in the morning with how comfortable this liner is. The mummy shape is perfect for any type of sleeping bag too, so you won’t have to deal with fabric bunching up uncomfortably. Not only that, but the fabric wicks away moisture from your body to keep you warm and dry. If you start to sweat during the night, you won’t have to worry about waking up wet and chilled.
– 27 degree rating
– Drawstring hood to prevent heat loss
– Very lightweight for a fleece liner
– Mummy design with a footbox
– 30 day money back guarantee
– Machine washable
– Not for ultralightweight backpacking
Though made entirely from polyester, the Vumos sleeping liner has a silky finish so that it feels better on your skin. Personally, I’m not a huge fan of silky material against my skin, but I know that many of you do enjoy it.
Coming in at 7 feet long, this liner can accommodate campers of any height with ease. The best part is that it comes with a full length zipper, so you can get in and out of it faster as well. If you’d like, you can even unzip it all the way and convert it into a bed sheet on warmer nights, or if you sleep on a cot or mattress.
– Budget friendly
– Full length zipper
– Plenty of room for tall people
– Packs down to a small size
– Feels cheap
– Material is slippery
While not necessary in every situation, liners can mean the difference between freezing at night and being comfortable. And if you don’t plan on camping in colder temperatures, they’re nice to have anyway, since they’re easier to clean than your sleeping bag. We like the Litume all season sleeping bag liner because it’s great for any weather condition. Rated at 27 degrees, it’s the perfect thing to keep you toasty in most situations, and it packs down well so you can shove it in your backpack easily.
The mummy design keeps heat trapped better, but there’s still plenty of room to wiggle around so you won’t feel claustrophobic. It also comes with a hood drawstring to cinch it around you head to whatever tightness you would like.
