Sleeping bag liners are one of the most undervalued gears in the camping world. It provides a string of benefits to both the camper and the sleeping bag:
Sleeping bag liners provide a layer of defense against grime, debris, small pebbles, and sand from settling within the insulation of the bag. Furthermore, they also absorb skin oils, sweat, and odor from the body before they reach the shell and surface of the sleeping bag. Therefore, using bag liners keep your sleeping bag cleaner for longer so you do not have to wash it as often. For this reason, it also helps maintain the quality and the loft of your bag.
It keeps you even warmer. Using sleeping bag liners could keep you warmer inside the sleeping bag by up to 15 degrees Fahrenheit. A sleeping bag liner serves as a thermal insulation to trap your body heat within the bag.
These also help to protect you from biting insects, aid in relaxation, and ensure that you have a good night’s sleep.
These are not only useful in backpacking trips. You could also use sleeping bag liners in hotels and hostels where the cleanliness of the beds is questionable.
When choosing a sleeping bag liner, make sure that the size and shape fits inside your sleeping bag well to ensure maximum comfort and insulation.
