As the name suggests, the Sea to Summit Reactor Extreme is a liner designed to be used in all weather conditions. It will keep you warm and tugged in anywhere from the seaside to the mountain peaks. That’s right; this liner will turn any outdoor space into a comfy bed that you’ll learn to love during your travels.

The sleeping bag is made out of insulating Thermolite fabric uniquely designed by the manufacturer. The fabric can keep you warm during cold days, but it also regulates your temperature on a hot summer night. The bag increases the temperature by about 25 degrees F, which is more than enough to keep you warm and snuggled in. The liner on the bag is a nice little touch because it keeps your bag clean and protects it from any dirt or grime getting in. This little detail prevents wear and tear giving the bag a long life expectancy.

Most liners that are worth something can keep your body warm, but your face is prone to the elements. Well, this bag will take care of that with the Drawcord hood that features a mini cord lock designed to lock around your face and keep it warm as well. It may seem like a feature you can do without, but spending one day in a cold environment will make you love this feature. The liner has a Mummy shape and a 3D foot box that provides more than enough space for your feet, even if you’re wearing boots.

The bag also comes with a useful and convenient Ultra-Sil stuff sack that makes it easy to carry and pack wherever you might find yourself. When we’re talking about sleeping bags, this one is one of the best models you can find on today’s market.

The Friendly Swede Travel and Camping Sheet

Sleeping bag liners are a must-have if you plan on camping or spending days on end in the wild. The problem with many brands and models is the size. The bags often take a lot of room and don’t provide enough of it, especially if you’re a bit taller or more extensive than the average person. Well, the Travel and Camping Sheet from The Friendly Swede is here to change all that.

It is one of those liners that undoubtedly provide enough space for almost anyone. The dimensions are 105 x 220 cm, and you also have a pillow pocket that increases comfort by far. You’ll feel like you’re sleeping on a hostel bed or a hammock rather than a sleeping bag. Moreover, it’s made out of super silky material that feels very soft and tender on your skin. The material is polyester you can wash in a machine without worrying about damaging it. The entire bag, pillow, and packaging are very light, weighing less than 240 grams or 8.35 ounces. That means that you won’t have to carry extra weight with you, but you’ll still have a very comfortable place to sleep in.

The bag liner has a 23-inch opening on the side that allows you to get in and out of it quickly. The bag has many benefits, but keep in mind that it’s not designed to be slept in where the weather is cold. You can use it outdoors or indoors, but not when it gets below zero. With that said, it’s still one of the most popular bags and most users are more than happy with the benefits it provides.

Traveling and backpacking around the globe requires you always to have all essentials with you. One of the things you just can’t do without is a sleeping bag liner.

The Cacoon Silk MummyLiner is one of the best choices you can make. It offers comfort, it’s compact, lightweight, easy to wash, and it’s also very durable.

Unlike cheap produts that are made out of polyester, this one is made out of silk that feels amazing on your skin. Silk is also an ideal material for sleeping bags as it’s breathable during warm summer months, but it also acts as an excellent insulator when it gets cold. The list doesn’t stop there. The silk is easy to handwash, and it dries out in a matter of minutes. Also, the material is very thin so that you can roll it up, and it won’t use a lot of space. You can cramp it in a smaller pocket on your backpack with ease.

The entire bag weights only about 5 ounces, making it one of the lightest bags on the market. With that said, it is still warm enough and it ads at least 5 degrees when you use it. Since it’s so light, this bag is not the ideal pick for those who want to conquer a mountaintop or spend a lot of time in a cold environment. But if you plan on traveling an area where it’s hot, this is the best sleeping bag liner you can get.

Benefits of High-quality Sleeping Bag Lineru

If you are the type of person that likes to go on long hikes and spend days on end in the great outdoors, a sleeping bag liner is one of the essential pieces of gear you’ll need. Apart from keeping you warm and dry, a sleeping bag liner also provides a number of benefits most people are not even aware of. Here are some of the positives you’ll get by using one of these bags:

  • Provides additional warmth

Depending on the materials used and the thickness of the bag liner, it can help you keep body heat inside of your sleeping bag. That can be useful when sleeping under the stars, especially in colder areas.

  • Great for all seasons

A liner can be your best friend in warm and cold weather alike. If it’s warm, the bag liner can work as a sleeping bag, and it also takes up less space than a standard bag. If it’s cold, you can use the liner as a second layer in the bag for more warmth.

  • Easy to wash and dry

Washing a sleeping bag is a huge drag. To get the best results you have to take it to dry cleaning, but the bag liner is much easier to take care of. You can wash it in any washing machine, you can wash it by hand, and once you’re done, leave it in the sun, and it will dry in a matter of minutes. You can do that on the road, washing the liner in rivers and creeks you encounter.

  • Comfort above all

Since the bags are silk, and not synthetic materials, it’s comfortable to sleep in. After a long day of hiking and outdoor activities, this bag liner will feel like a king size bed in a five stars hotel. Comfort is perhaps the biggest benefit to using a sleeping bag liner.

  • Protection for your sleeping bag

The sleeping bag liner has another role – to protect the sleeping bag from grime and dirt giving it a longer life. Using a liner in an expensive sleeping bag makes a lot of sense. It’s easier and cheaper to get another liner than another bag.

What to Look For In a Sleeping Bag Liner – Buyer’s Guide

The market for sleeping bags is vast. There are many different manufacturers, brands, and models. You have to know that not all bags are made to be used in the same environment. Not only that, but they can be made out of different materials and a different purpose. Knowing which one you need can sometimes be a problem, which is why we created this small guide that can help you figure out exactly what you need. So, let’s take a look at the things you should consider before purchasing a sleeping bag liner.

The Materials

Sleeping bag liners can be made out of a number of different materials like silk, fleece, cotton, polyester, and merino wool are the most common. There is no ideal material as it’s a personal preference based on the way it feels on your skin. However, cotton liners are very popular because they are super comfortable, but they tend to soak up moisture and become wet and useless. Silk liners are light and comfortable, but they are less durable than let’s say polyester. Fleece liners are cheap and reasonably warm, but they weigh a lot and take up too much room. Merino wool is the lightest, warmest and most comfortable, but they are the most expensive as well.

Heat Rating

You can find the information about the temperature rating of each bag in the reviews. The heat rating is critical as it tells you how many degrees can the liner provide additionally. The warmest liners on the market can provide from 15 to 25 degrees, but you should be aware that they are pretty expensive so be ready to spend money if you want to stay warm at all times. If you plan on spending a night in a sleeping bag in an area with cold weather, make sure you bring a liner with you because those extra 15 degrees make a huge difference in your experience. Besides, it’s better you are prepared for any situation.

The Weight

When buying a sleeping bag liner, you have to make some compromises. Do some research on the area you are planning to camp at and see what are the expected temperatures during the nights. The more degrees your liner provides, the heavier and bulkier it is. So, you need to figure out if carrying some extra weight is worth it or not. Liners are not that heavy, most of them weigh less than a pound, but even that can be too much on a long hike. As we said, do some research and get the liner that fits your needs best.

The shape of the liner

Sleeping bag liners come in a variety of different shapes. The most popular ones are the mummy and rectangular shapes. Again, you have to figure out if you want to have more room inside of the bag, or do you prefer a tight fit when you sleep. Rectangular sleeping bags usually have a couple of features you can customize, and they offer more space, but mummy shaped liners are better at keeping you warm than others. Some models even feature a drawstring that allows you to entirely cover yourself up with the liner, making sure that all of the heat stays inside.

Bug Protection

Some people are really into cowboy camping, or camping without a tent, which is nice because you get to sleep under the stars, but it also has some drawbacks. The most significant issues with no-tent camping are the bugs that will be flying and buzzing all around you. If that is the case with you, look for a liner made out of insect-resistant fabrics. That should be enough to keep the creepy crawlies away, but it’s also a feature that will cost you more than a standard liner. If you ask us, it’s always best you get the one that will keep the bugs away. No one likes to feel something crawling around the bag in the middle of the night, right?


Spending a night in a sleeping bag can create a lot of steam. The insides of the bag are designed to keep the warmth inside, which means that you’ll sweat through the entire night. That can be an issue especially if you’re using a bag that’s too warm for the situation you are in. Well, a good sleeping bag liner can help you get the excess moisture produced by sweating out of the bag. It allows it to breathe, which is a nice feature many learned to love.

In Conclusion

Spending a night outdoors can be a great experience, but it can also be a bad one if you don’t have the right gear. A sleeping bag liner is part of the essential equipment you have to have with you if you plan on sleeping under the stars. Take some time to get familiar with the bag liner types and the benefits they provide before buying something you won’t need. They will keep you warm during the night and allow you to breathe inside of your sleeping bag if things get too hot. All in all, you can’t be a serious camper and outdoor lover without a quality sleeping liner, that’s for sure.
