Can You Wash a Down Sleeping Bag?

Whether you’re an avid camper or you just like to be prepared for any situation, you may be wondering if you can wash a down sleeping bag. The good news is that you can, but there are a few things you need to keep in mind.

Down sleeping bags are filled with natural or synthetic fibers that provide insulation. When these fibers get wet, they lose their ability to insulate, which is why it’s important to make sure your sleeping bag is dry before storing it.

Washing a down sleeping bag is similar to washing a down jacket. You’ll want to use a mild detergent and a front-loading washing machine. Avoid using a top-loading washing machine, as this can damage the fibers.

So, how Do You Clean a Down Sleeping Bag?

To clean a down sleeping bag, you will need a mild detergent, a large washing machine, and a dryer. Before washing, check the sleeping bag for any rips or tears.

If there are any, repair them with a sewing kit. Then, place the sleeping bag in the washing machine on a gentle cycle.

Add the detergent and wash according to the manufacturer’s instructions. Once the cycle is complete, remove the sleeping bag and place it in the dryer in a low heat setting. When the sleeping bag is completely dry, store it in a cool, dry place.

Is a Down Sleeping Bag Ruined if It Gets Wet?

It is often thought that if one gets their down sleeping bag wet, it will be ruined. However, this is not the case. Down sleeping bags are designed to withstand moisture and can easily be dried out.

So, if you find yourself in a situation where you need to get your down sleeping bag wet, don’t worry, it’ll be just fine.

If you’re caught in the rain with your down sleeping bag, don’t despair—you can still salvage it. First, shake the bag out to get rid of as much water as possible.

Then, put the bag in a dryer on the lowest setting, along with a couple of tennis balls to help fluff it back up. If you don’t have a dryer, you can lay the sleeping bag out in the sun (if it’s not too hot) or in front of a fan. Once it’s dry, your sleeping bag should be as good as new.

If you have a wet-down sleeping bag, there are a few things you can do to dry it out. However, a down bag will take several hours to dry thoroughly. Insulation loft is key to keeping warm. As for both down and synthetic fills, you need to fluff up (loft) to create small air spaces within the insulation. These spaces trap body heat to help you stay warm while you sleep. If your bag is wet, you can try to fluff it up by shaking it and/or putting it in a dryer on low heat for a short period.

Here Are Some Tips for Drying a Down Sleeping Bag:

  • Setting the dryer on low heat is always the best option for delicate nylon fabrics. High heat can potentially melt the fabric, so it’s better to play it safe and dry on low heat for a longer period of time. This may take a bit longer, but it’s worth it in order to keep your clothes in good condition.
  • If you are able to use a commercial-size dryer, it is ideal for fully lofted sleeping bags. The larger capacities of commercial dryers allow for the sleeping bag to tumble, which is necessary for even drying. If you don’t have access to a laundromat, you can use a home dryer, but it may not be large enough to fully loft the sleeping bag.
  • Completely drying the bag requires multiple cycles and patience. Let the machine run for at least an hour, but it will probably take longer. Check on the bag periodically to ensure that it is drying completely.
  • There are a few different ways that you can dry your bag if it gets wet. One way is to lay it flat on a clean surface in an area with low humidity and no direct sunlight. This will take longer to dry, but it will ultimately be effective. Another way to dry your bag is to hang it up. This is a good option if you are careful to distribute the weight so that you do not put too much stress on the nylon fabric.

How Often Should You Wash a Down Sleeping Bag?

Down sleeping bags do not need to be washed very often. In fact, washing once after a long season or only when needed.

However, we suggested hand washing your down sleeping bag once every 10 used in order to protect the delicate down feathers. In between, you should always dry out after every use and keep it in a cool and dry place.

To hand wash, fill a bathtub with cool water and a bar of mild soap. Gently massage the soap into the sleeping bag, taking care not to agitate the feathers too much.

Rinse the sleeping bag thoroughly, and then gently squeeze out the excess water. Lay the sleeping bag out to air dry in a cool, well-ventilated area.

Yes, you can use Woolite to wash your sleeping bag. Woolite is a gentle detergent that will not damage the fabric of your sleeping bag. It is important to follow the instructions on the Woolite label when washing your sleeping bag. Always use cold water and a gentle cycle when washing your sleeping bag. Do not use bleach or fabric softener. When drying your sleeping bag, use a low heat setting or air dry.

Yes, you can use vinegar on a down sleeping bag. The vinegar will help to break down the oils and dirt that have built up on the down feathers, and it will also help to freshen the fabric. You should dilute the vinegar with water before using it on your sleeping bag, and you should always test it on a small area of the fabric first to make sure that it does not damage the fabric.


In conclusion, down sleeping bags can easily be cleaned using cold water and a soft cloth. I would suggest washing them by hand, as machine washing can rip or weaken seams. Down sleeping bags is a great investment for anyone who loves to camp, as they provide warmth and comfort in any situation.
