How to choose the Best Sleeping Bag Liner

Weight & Compressibility

While backpacks, sleeping bags, tents and other outdoor gear add on to a significant amount of weight, we don’t want another bulky item in our backpacks. While these liners are generally less in weight, make sure they are also easily compressible and have a compact packed size.


If you are looking at sleeping bag liners to add a layer of warmth, silk is a winner. Fleece and Microfleece liners also give warmth but are bulky. The rest, just make sure your sleeping bag does not get dirty.

Fit / Shape

Some sleeping bag liners are designed specifically for mummy bags, which might be what you need. They are generally rectangular in shape and fit in both mummy bags and quilts.


The material of sleeping bag liners determine the comfort you get from it. Deciding it isn’t a complex science, rather a personal choice based on a few key factors.


Silk liners are the lightest of all, and are very compact as well. They are helpful with insulation in cold weather and still remain absorbent and breathable in warmer weather.

Silk Sleeping bag liners require delicate care, and come under the expensive ranges.


Cotton liners are strong, absorbent and breathable. But they are not as lightweight and compact as silk liners.

Cotton Sleeping Bag liners are affordable and durable.


Synthetic liners are usually preferred for humid conditions, as they are absorbent and moisture-wicking. Moisture-Wicking simply means that the fabric can move sweat to the outer surface of the fabric, and can dry quickly.

Synthetic sleeping bag liners are priced moderately.

Fleece and Microfleece

This type of sleeping bag liners add a lot of warmth and comfort. They give a cozy feeling against your skin while sleeping. However, they are bulky and are not quite useful in warm weather.

Advanced Features

Bug Repellent Liners

These type of sleeping bag liners are subjected with protection treatments at the final stage, to repel insects, mosquitoes, ticks, fleas, etc. Liners that come with an anti-bacterial finish protect the bag against odors caused by bacteria.

The Sea to Summit Adaptor CoolMax Sleeping Bag Liner is one such liner that you can get with Insect shield.

  • Cozy and Comfortable
  • Lightweight
  • Perfect for Mummy bags
  • Stuff sack included
  • Made of high quality Polyester
  • Great value for money


  • No zippers make it difficult to get in and out of the bag

Short Review

Made out of brushed Polyester, the ALPS Sleeping Bag liner is soft and durable. It conveniently packs into a compact bag and is very easy to carry around. 

It is a mummy style liner but can be used comfortably in both mummy and rectangular sleeping bags. You also have the same bag in Polycotton which can be bought here - ALPS Mountaineering Poly Cotton Mummy Sleeping Bag Liner

One shortcoming of the liner is that it does not have zippers, which can make usability a bit difficult.

Priced reasonably, this sleeping bag liner makes for a valuable addition to your gear.


  • Spacious & Comfortable
  • Side opening to easily get in and out
  • Silky smooth
  • Ultralight at 178 grams
  • Great for backpacking
  • Machine washable
  • Included packing bag
  • Good packed size


  • Little slippery
  • Velcro snaps at times

Short Review

The Dimples Sleeping Bag Liner is a cotton sleeping bag liner that is spacious and accommodates even taller and broader people comfortably. It’s made of cotton with a soft texture to feel great against your skin.


What we loved about the liner is that it is a balance of all good features - space, comfort and weight. It weighs 178 grams and is perfect for your backpacking trip. It comes with a packing bag in which you can tuck in your liner easily. For a cotton liner, it packs down to almost nothing.

It has a side opening that is great for usability, that makes getting in and out of the liner a breeze. 

Being super soft also has a disadvantage  - it gets slippery at times. While this is the only major drawback of the liner, overall it is a great liner at a reasonable price.


  • Compact folded size
  • Included pillow pocket
  • Side opening zippers all the way down to get in easier
  • Rectangular design can be used for both mummy bags & quilts
  • Washes & Dries easy
  • Contributes to 5-8F warmth
  • Made of high quality Polyester
  • Lifetime Warranty


  • A tad heavy for backpacking

Short Review

The Friendly Swede Sleeping Bag Liner is a budget friendly addition to your outdoor gear. Made of Polyester, it has a silk texture that’s super soft against your skin. Weighing 5.6 ounces, it is one of the lightest in our reviews, and also super spacious. 

One interesting feature of the liner is the full length zipper or velcro at its left side. It helps you get in and out of the sleeping bag liner with ease. It includes a pillow pocket for packing the sleeping bag, and is machine washable.

One shortcoming of the liner is however, the length of the bag. For tall people, it might be an issue. But being the cheapest out of all the bags in our review, the liner is a good pick.


  • Excelled packed size
  • Silk cloth gives super soft comfort
  • Comes with a hood
  • Warm and Cozy
  • Spacious
  • Easily washable and durable


  • Very thin so provides only a small measure of added warmth

Short Review

The Cocoon Silk Mummy Liner is an excellent choice for a silk sleeping bag liner. Made of Ripstop silk, it is robust and durable and super soft.

It can be easily machine and hand washed, and also dries quickly. Though the manufacturers claim that it is great for the summer as well as winter, in extreme weathers it might not be something that you can rely upon to add temperatures. It packs down very compact and might be just what you need when you are planning an ultralight backpack.

Coming at various color options, the liner is visually appealing as well. 

However, there is one drawback to the liner.  Some users have felt that getting in and out of the bag could have been more comfortable.


  • Lightweight
  • Made of durable materials
  • Easy to wash
  • Comes with a stuff sack
  • Perfect for mummy sleeping bags


  • Insect Shield tends to wear off with time
  • Thin layered

Short Review

The Sea to Summit  Sleeping Bag Liner is made of CoolMax fabric, which is specifically designed with moisture-wicking properties. It is lightweight, dries quickly and is machine washable. 

The liner is made of Polyester, and no doubt gives you a comfortable night’s sleep. It is a mummy shaped liner that is a great fit for most of the sleeping bags, and sliding into is also is a very easy task. When done, it packs up compact into the stuff sack it comes with, neat and tiny. 

You have an option to buy it along with the insect shield, but in our testing we have found that the insect repellant tends to wear off after a couple of washes. If asked which is the best use for this liner, I would say to keep your sleeping bag clean. It didn’t prove to add warmth in cold weather.


Choosing a sleeping bag liner isn’t complicated. We only need to consider some key factors while buying one. 

First would be the material you want it in – Silk, Cotton or Polyester. Next would be the weight, packed size, fit and price of the liner. 

While taking into account all the above factors, we have found the DIMPLES EXCEL Sleeping Bag Liner to be the best. It meets all the criteria somewhere in between, and is a great value addition to your next trip. It is also spacious for all builds of people, and has a full side opening to get in and out easily.

I have a serious thing for travel, outdoors and wilderness. I grew up in Oregon and camping outdoors with my father was one of the fondest memories of childhood. I enjoy camping and hiking and love to share what I've learnt over these years.
