Will a Sleeping Bag Liner Make You Warmer?

Is a sleeping bag liner worth adding to your camping and backpacking gear? Will it actually help keep you warm? Here are a few things to consider.

Liners Create Layers

The extra layer that sleeping bag liners create allows more air to become trapped. This process creates extra warmth.

Liners Protect Bags

Perspiration, dirt, and body oils are all naturally occurring substances that can have a detrimental effect on your sleeping bag and its ability to provide maximum warmth. A sleeping bag liner acts as a buffer, absorbing these bodily materials so the thicker, warmer sleeping bag can effectively do its job.

Liners Stay Clean

Repeatedly washing a sleeping bag can actually wear out the bag itself and cause it to be less effective at trapping air and keeping you warm. This problem is one reason why sleeping bag liners can be very useful to campers and backpackers. Liners are easier to remove, wash, and replace than the actual sleeping bag.

Liner Size is Crucial

It is very important that your sleeping bag liner is the proper size and fits perfectly inside your sleeping bag. A poorly fitted liner will not provide adequate warmth.

Sleeping bag liners are an excellent way to add extra warmth for chilly camping evenings.
