What to Consider

A sleeping bag liner is a handy addition to your survival kit as it lines your sleeping bag.

Liners are made from both thick or thin (lightweight liners are more practical) materials, and therefore can vary in weight, and shaped like a cocoon. Its purpose is to act as a barrier between you and the actual sleeping bag itself.

The best sleeping bag liner can be slept in when wearing clothes and when wearing no clothes whatsoever.

A more straightforward way of looking at a sleeping bag liner is to compare it to a bedsheet during your outdoor living (surviving!)

Like all additions to your survival kit, it is essential to do your research and consider many factors before finalizing any purchases.

This buyer’s guide will assist in making your final decision on both what delivers in quality and best suits your survival experience.

The Climate You’ll Find Yourself In

It is crucial to examine the climate you plan to camp in before attaching yourself to just any sleeping bag liner.

Sleeping bag liners are manufactured in a few different types of materials, to entertain various weather conditions.

Silk liners are the most lightweight liners and are best suited for summer conditions, but if you’re looking for added warmth, then it will be best to look at other materials.

Alternatively, fleece liners are the best for adding warmth to your bag in cold climates. An insulated liner can raise the temperature inside the bag by up to 25 degrees F, if well made.

Heat Rating

If added warmth is essential to your chosen sleeping bag liner then it is wise to double check the temperature rating in the specifications, which is usually provided by the company.

The number indicates the additional amount of warmth it can provide, and it’s worth noting that the warmest backpacking liners are rated up to 15-25 degrees.

The Liner’s Fit

Although they usually come in a cocoon shape, sleeping bag liners come in several different forms.

Some backpacking liners on the market accommodate those who aren’t of average height or weight and are usually shorter or longer than usual to make sure the liner can match the sleeping bag’s length and width.

Mummy liners provide extra warmth because it forms to the shape of your body, and traps heat while doing so. However, this can be constricting, and if you wriggle in your sleep, it may cause disturbance and discomfort in your sleep.

Weight and Compressibility

You are backpacking and, therefore, won’t want a liner that hinders your every move. Backpacks, especially in a survival setting, will likely be packed to the brim with equipment.

Since most backpacking liners have thick material, they tend to take up a good amount of space.

That’s why it’s essential to acquire a lightweight liner that will fold up much smaller to fit in your pack without having to rearrange your entire kit.

Material of Liner

The lighter weight sleeping bag liners tend to be made from silk and synthetic materials and will benefit your back and take up less space in your backpack since they’re more compact.

The breathability of silk and synthetic backpacking liners is better, which is ideal in hotter climates.

Fleece and insulated liners are more cumbersome and will take up more room in your backpack, but will provide extra warmth to your adventure.

They are best suited to colder climates, and the advantage of this type of liner is they are quick-drying and moisture-wicking, so you won’t have to worry about a damp bag the following evening.

Breathability

If you’re a known sweater or the climate you’ll find yourself in will be wet, it might be worth to find a liner with a “CoolMax” trademarked feature on it, which will prevent moisture in your sleeping bag.

Sleeping bags, whatever the material, can get steamy, and you want your liner to help wick any moisture away from your body for ultimate comfort and ease.

Bug-repellant Liners

If you find yourself setting base without a tent, then bugs will inevitably occur. Even with a tent, bugs can greet you unwillingly.

To prevent this issue from arising, you might want to find yourself a liner that comes with insect-resistant coated fabrics to deter any unwanted camping companions.

Pillowcase Liners

Pillowcase liners are deal for trips when you aren’t able to shower for long periods, as they protect your pillow from dirt, and save you from cleaning it more than you have to.

It isn’t a fundamental inclusion but is a consideration to take into account before you choose the best sleeping bag liner for you.
