How to Choose the Best Sleeping Bag Liner for Your Needs?

Sleeping bag liners are a super useful item to travel within my option. They are very versatile and don’t take up much space in your luggage so I can’t think of a reason not to carry one, given all the benefits.

For example, a good sleeping bag is expensive and you’ll want to avoid washing it too much in order to prolong its life.

A sleeping bag liner means that you can keep your sleeping bag clean and not have to wash it, by washing the liner instead.

A good sleeping bag liner can also add a season of warmth to your sleeping bag, making a good 3 season bag capable of withstanding winter temperatures.

Some liners are also moisture wicking, helping you to stay dry and warm.

When traveling in hot places, the sleeping bag liner can take the place of your sleeping bag completely. I can speak from personal experience having done this for 3 months in South East Asia.

And finally, there’s the hygiene factor. Sleeping bag liners can provide you with a clean surface to sleep on when you’re not completely sure about the cleanliness of your lodgings.

They also help to prevent bites from bed bugs and mosquitoes (though this depends on the material).

But, there are different kinds of sleeping bag liners. So you’ll need to decide which factors are important to you.

Shape

Rectangular or Mummy shaped?

This is a personal preference and depends on how much leg room you need.

Size

If you want to use your liner inside your sleeping bag, you’ll want something a little smaller/less bulky.

If you’re a taller person, you may need a longer liner.

Entry

Do you mind shimmying in through a top only entry or do you need a side opening?

Zips can be handy for easy access but take up space when packed and can be more hassle than they’re worth if they tend to snag.

Material

This is actually probably the most important factor. Sleeping bag liners can be silk, cotton, polycotton, polyester or fleece.

  • Silk is the most expensive, but it is the most versatile in hot and cold temperatures, it packs down to the smallest and lightest package, and it doesn’t need to be treated against insects as bed bugs and mosquitoes can’t penetrate the fine mesh (although there will be nothing stopping them from entering at your head end).
  • Fleece can be cozy and warm but will be bulkier.
  • Cotton is usually heavier and once it gets wet, will stay damp and not help to keep you warm.
  • Polycotton or polyester can be a great choice depending on the quality, basically being a combination of fleece and silk in properties.

Waterproof sleeping bag liners are not very common, as waterproofing adds weight and bulk, and reduces breathability.

But if it’s something you’re really determined to find, Brolly Sheets do a waterproof sleeping bag liner that is about the size and weight of a flannel sheet when packed.

Summary

So that concludes this article on the best sleeping bag liners for travel.

I hope you found this article useful.

I believe sleeping bag liners can be a really great addition to your travel gear, especially if you choose one that is light and compact.
