But, you can try to wear clean socks and underwear, and clean your face and keep the dirt off by using a sunscreen that you will wash off before sleep. If the weather is warm, then you can change into a clean shirt and underwear. If you get into the sleeping bag with all the dirt on you, it will affect the insulation of your sleeping bag.
  2. Sleeping bag liner: Another good option to keep your bag clean is to use a liner. They are made of cotton, polyester, silk or wool, and are light in weight. They act as a separating screen between your skin and the sleeping bag, and keep the dirt off of your bag. Additionally, they add 5 to 10 degrees Fahrenheit to the bags temperature rating. You can wash the liner at the end of your trip and you can take it to another trip.
  3. Ground protection: In case that you have to sleep on the ground, you need to put a pad under your sleeping bag to protect it from the ground. Even if the bag is waterproof it will need protection against sharp sticks and conifer terrains.
  4. Treat it with care: Treat your bag gently and don’t jump around while you are in it. If you want to wrap around the bag while sitting near the fire, you should bring an older synthetic bag. Nobody wants to see holes due to sparks, on their brand new bag.
  5. Use zippers gently: Zippers can be a bit tricky sometimes, so, if you want to zip up your bag easily, practice it at home. Use the zipper gently so that you don’t yank it or snag it. If the zipper is two ways, then it may be frustrating for you, be patient so that you don’t cause a fabric tear.
  6. Airing out the bag: Never leave your bag in the sunlight for very long because the UV rays can be harmful to the fabric. If the bag is wet, then wait for the moisture to air out.
