Sleeping Bag Liner Buying Guide

These camping accessories may be fairly simple, but the different products vary in a big way! Here are some important things to consider before finding the right sleeping bag liner. 

 

Shape and Size

Sleeping bag liners come in a variety of shapes and sizes. These will make a big difference in your experience with them. There are two shapes to choose from: mummy shape or rectangular liners. Both have their pros and cons – but be sure to choose the same shaped liner as the sleeping bag that you use.

Also, check out the size. Some people prefer a snug fit, while others want more room to kick around in. This is also important to remember when pairing up to your sleeping bag.

Material

The top sleeping bag liners are available in all kinds of different materials. You can choose between a silky finish, a fleece liner, or even a cotton sleeping bag liner. Some products are fairly weatherproof (perfect for hiking and camping), while others offer a more soft and luxurious experience with moisture wicking properties.

Travel-Friendly

When you go camping, there is often so much equipment involved. When adding a liner to your load, you won’t want it to weigh you down. Most sleeping bag liners are specially designed to be lightweight and easily portable.

If you are planning a hiking trip or going backpacking, then try to get the most travel-friendly option. Have a look at the liner reviews to find out how easy it is to pack away, and whether it can be attached to your backpack.

Durable

If you are camping out in all kinds of different areas, you will definitely want your equipment to be tough. Look at the materials used and make a note of whether these have double stitching and will be durable enough when exposed.

Some sleeping bag liners are very soft and comfortable, but are not particularly hardy when used alone or unprotected.

Final Thoughts

With a sleeping bag liner, you can easily take your sleeping experience to the next level! These simple camping hack accessories are such a great way to improve your night’s sleep in terms of warmth, comfort, and hygiene.

Whether you are after a soft silk finish, a warm fleece blanket, or a thermal mummy bag, there is a liner out there that can do it!
