Sleeping Bag Liner: Ensuring Restful Nights in the Great Outdoors

If you are camping, hiking or just outdoorsy you know comfort and warmth are essential to your experience. And to make this even better, I have a game changer for you: the Sleeping Bag Liner. But what is it, and so why do you need it? Let us go into the details and find out about this crucial piece of outdoor equipment.

Sleeping Bag Liner – Why Use One?

Using a sleeping bag liner can make camping more enjoyable. It has multiple benefits beyond providing extra comfort. For outdoor enthusiasts and adventure seekers a sleeping bag liner is an add-on, not a necessity. It has numerous benefits that directly benefit your well-being in nature.

The sense of familiarity that a liner provides is one of the main reasons for using one. A liner makes a bed in the wilderness whether you are taking it on a month long expedition or a weekend camping excursion. Plus it helps to slide into a clean, soft liner after an outdoor day. Lastly, a sleeping bag liner acts like a shield for those with sensitive skin. Because it blocks off the sleeping bag from you, it may prevent irritation or allergies from the material of the bag. Consequently, it lets you sleep soundly and wake up refreshed for the following day.

Add Warmth

The added layer of a liner can provide plenty of warmth on those cold nights. Although it may be the sleeping bag itself that provides the warmth, the air trapped inside is, contrary to common misunderstanding. The liner traps more heat that your body can warm, increasing the heat retention capacity of the bag.

Other than the extra layer, some liners have thermal properties which add to their heat retention ability. These liners are typically made of silk, fleece, or thermal material and add up to 25′ F to your sleeping bag temperature rating. Thus a liner keeps you warm in cooler temperatures while extending the usability of your sleeping bag throughout the year. Regardless of whether you are camping in summer time or the cool winter, a liner keeps you warm in your sleeping bag.


Camping can be dirty. Some of the grime comes back into the sleeping bag after a day hiking, climbing or just exploring. Liner protects your bag from dirt, sweat, and body oils. The best part of a sleeping bag liner is it is easy to clean. After your trip, just pull the liner out and wash it instead of cleaning the whole sleeping bag (which can be very cumbersome).

And using a liner can be especially helpful if you are renting or borrowing a sleeping bag. Who used the sleeping bag last or how clean it is, but with a liner you have a clean bed to sleep in no matter what.

Longer Lifespan of Your Sleeping Bag

The cost of a good sleeping bag can be heavy on the pocket. Consequently, it should be long lasting. This is where a sleeping bag liner can help. A liner also reduces wear and tear on the sleeping bag.

The repeated packing and unpacking of a sleeping bag can cause wear and tear on its materials. But a liner can mitigate this by taking much of this stress on itself. As well, a liner prevents dirt and oils from building up and wearing away the material and insulation of the sleeping bag over time. Therefore, a sleeping bag liner is a comfort accessory as well as a protection tool for your sleeping bag investment.

Types of Sleeping Bag Liners.

Sleeping bag liners come in numerous materials with varying benefits and drawbacks.

Silk Liners

Silk sleeping bag liners are a luxury for camping. They’re light and pack down to a small size – ideal for trekkers and backpackers who wish to haul a light weight. Silk is also very soft against your skin so you can relax easily. But the silk liners are more than just for comfort. Silk is a thermal material. It could keep you cool in warm weather and hot in colder weather. Thus a silk liner can make your sleeping bag suitable for a wider range of climates.

Another benefit of silk liners is they’re hypoallergenic – therefore they’re a great option for a person with very sensitive skin or allergies. Silk is also resistant to odors and dirt, which can lengthen the intervals between washes – an important property on long outdoor trips.

Cotton Liners

Many outdoor enthusiasts use cotton sleeping bag liners, which are inexpensive and durable. They have a homey feel – like your bed sheets – and provide a comfortable sleeping environment – even if you’re miles from home. Cotton is very breathable. A cotton liner can keep you from getting sweaty or stuffy inside the bag, so you can sleep soundly asleep. It’s also naturally hypoallergenic, so it’s suitable for sensitive skin or even allergies.

However, cotton liners are not the best – both in weight and packability. They are heavier and bulkier than silk or synthetic fabrics. Cotton also takes longer to dry if it is wet. Despite these cons, many campers choose cotton liners because they are comfortable, durable and less expensive.

Synthetic Liners

Artificial sleeping bag liners are a good compromise between silk and cotton, usually from microfiber or polyester. They combine the benefits of both materials and are a versatile choice. In terms of warmth, synthetic liners are comparable to silk liners and retain heat as well. They can provide enough warmth to make your sleeping bag useful in colder climates. Also, nearly all synthetic materials are quick-drying and moisture-wicking so you’re dry through the night.

Durability is another strength of synthetic liners. They can withstand frequent use and washing and are suitable for long, strenuous trips. They are also oftentimes less expensive than silk liners, making them a budget friendly option.

Synthetic liners provide comfort, warmth, durability, and low cost. Nevertheless they might not be so soft as silk or cotton liners and some might be slightly less comfy.

Choosing the Right Sleeping Bag Liner

Choosing the right sleeping bag liner is a critical decision.

The Shape

The shape of your sleeping bag liner is important for comfort. The two main shapes are mummy and rectangular. Mummy liners are shaped like mummy sleeping bags and retain body heat well so they are ideal for cold weather. They’re usually lighter and less bulky. Rectangular liners are more like bed sheets and allow more movement for those who toss and turn or feel claustrophobic in small spaces. They’re however, less efficient at retaining heat. Choosing mummy or rectangular is down to personal preference and sleeping bag type.

It Is The Material

Warmth, weight, packed size, and skin feel all depend on the material of your liner. Silk liners are lightweight and breathable, and maintain a moderate temperature but are costlier. Heavier and slower to dry, the cotton liners are tough and hypoallergenic (like traditional bedding). They tend to be cheaper than silk or synthetic liners. Synthetic liners, balancing cost, durability and performance, can add warmth and dry quickly to sleeping bag. They may not be as soft as silk or cotton liners. Choose a liner material based on your needs, budget and camping conditions.

The Size

Your liner should fit your sleeping bag comfortably. Too small a liner may limit movement, and too large a liner may reduce warmth by creating air pockets. Most sleeping bags will fit standard size liners, but double-check dimensions before buying. If you are tall or need more room to move while sleeping, you might want a bigger liner. For sharing the sleeping bag, a double-sized liner may be sufficient. The right size should be both comfortable and warm.
