Buying Guide

When looking for the best sleeping bag liner, there are a few key features to consider. Here are some factors to keep in mind when making your decision:

Material

The material of the sleeping bag liner is an important factor to consider. Liners can be made from a variety of materials, including cotton, silk, and synthetic blends. Cotton liners are durable and easy to clean, but they are heavier and bulkier than other materials.

Silk liners are lightweight and compact, making them a great option for backpackers, but they are less durable than cotton or synthetic blends.

Synthetic blends are a good compromise between durability and weight, and they are often treated with antimicrobial agents to prevent odors and bacteria.

Size and Shape

Sleeping bag liners come in different sizes and shapes, so it’s important to choose one that fits your needs.

Rectangular liners are the most common and provide the most room to move around, but they can be bulky and heavy.

Mummy liners are more compact and lightweight, but they can be restrictive and uncomfortable for some people. Make sure to choose a liner that fits your sleeping bag and provides enough room for you to move comfortably.

Temperature Rating

Some sleeping bag liners come with temperature ratings, which indicate the lowest temperature at which the liner will keep you comfortable.

Make sure to choose a liner with a temperature rating that matches the conditions you will be sleeping in.

Keep in mind that temperature ratings are subjective and can vary based on factors such as your metabolism and the amount of insulation in your sleeping bag.

Additional Features

Some sleeping bag liners come with additional features, such as built-in pillows, zippers, or pockets. Consider what features are important to you and choose a liner that meets your needs.

Keep in mind that additional features can add weight and bulk to the liner, so make sure to choose a liner that strikes a balance between functionality and portability.

Why Trust?

At Crave the Planet, I’m all about honest and relatable reviews of outdoor products. As a physical therapist, hut to hut hiker, downhill skier and mom, I’m constantly trying new gear to make my outdoor experiences more comfy and fun but with science in mind.

I’ll be real with you, I don’t do every outdoor activity. But, who does? I’m just a regular person who loves exploring the planet. Perfectionism is my enemy and I hope to help you ditch that vibe too.

My review process involves testing each product in real-life outdoor situations, but if it’s a really horrible day I’ll probably find a hotel in the valley. I’ll let you know what worked for me and what didn’t, so you can make informed decisions about your gear choices.

I don’t do sponsored reviews or take payment for my reviews. All comments are based on my personal experience. Sometimes I’ll test something and then send it back for a refund. Usually there’s a hefty fee. Bummer. So, if you’re looking for a relatable and honest take on outdoor gear, you’re in the right place.
