Down sleeping bags are lightweight and easy to transport, but they can develop an unpleasant odour over time. This is usually due to a variety of factors, including sweat, dirt, mildew, mould, and manufacturing defects. Body oils and dirt can accumulate on the bag if regular hygiene practices are not followed, and natural environments often have humid air, which can cause the bag to absorb moisture and develop mould or mildew. In some cases, the bag may not have been properly cleaned during manufacturing, resulting in a persistent odour. To prevent and address these issues, it is important to keep the bag dry, store it properly, practice good hygiene, and wash and dry the bag using appropriate methods and detergents.

What You'll Learn
Poor hygiene
To maintain basic hygiene and minimize the transfer of dirt and sweat onto the sleeping bag, it is recommended to clean yourself before bed. This can be done by showering near a water source, using wet wipes or a damp rag, or at the very least, changing into clean clothes before getting into the sleeping bag. The clothes worn during hiking can absorb sweat and dirt, and sleeping in them can contribute to the odour.
Additionally, using bag liners can provide a barrier between your body and the sleeping bag, reducing the amount of dirt and sweat that comes into direct contact with the bag.
It is also important to keep your sleeping bag clean during outdoor activities. Hanging the bag out in the sun or misting it with a gentle odour remover can help prevent mild odours. For more stubborn smells, washing the bag with a special down wash and tumble drying on low heat may be necessary.
Proper drying and storage of your sleeping bag are crucial to prevent odours caused by mildew and mould growth. Ensure that your sleeping bag is completely dry before storing it in a dry area at home. Hanging the bag is preferable to storing it in a bag, as it allows for better air circulation.

Body oils and sweat
To prevent body oils and sweat from causing a smell, it is important to maintain good hygiene practices while using the sleeping bag. This includes regularly washing the body and changing into clean clothes before entering the sleeping bag. Additionally, airing out the sleeping bag whenever possible can help prevent the accumulation of body oils and sweat.
If the sleeping bag has already absorbed body oils and sweat, it is important to clean it properly. Some people recommend washing the bag in a front-loading machine with a gentle cycle and a specific down detergent. It is important to avoid using regular detergent as it can strip the natural oils from the down feathers. To ensure the detergent is thoroughly rinsed, it may be necessary to run the machine multiple times without adding more soap.
After washing, it is crucial to dry the sleeping bag completely before storing it. Inadequate drying can lead to the growth of mold and mildew, which can cause unpleasant odors and potentially impact your health. To enhance the drying process, some people suggest adding clean tennis balls or sneakers to the dryer, as they help break up down clumps and re-fluff the bag.
In summary, body oils and sweat can cause a down sleeping bag to smell. To prevent and address this issue, maintain good hygiene, air out the bag, and follow proper cleaning and drying techniques.

Moisture and mould
Mould, mildew, and bacteria are common causes of a smelly sleeping bag. These microorganisms thrive in damp environments and release acids that can break down the natural oils in the feathers. Even if you don't feel any moisture, it is likely present in small amounts, causing a musty odour. Therefore, it is essential to keep your sleeping bag dry and store it properly to prevent the growth of mould and mildew.
If your sleeping bag has a mild musty odour, airing it out in the sun for a day or two may be sufficient to eliminate the smell. Fresh air and sunlight can effectively remove odours, and hanging the bag is a better storage option than keeping it in a bag. Additionally, you can mist the bag with a gentle odour remover like Febreze to mask the smell, although this will only work on the shell material and not the down filling.
For more stubborn odours caused by mould or mildew, washing the sleeping bag is necessary. Down sleeping bags can be washed in a standard washer, but it is important to use a special soap designed for down items, as regular detergent can strip the natural oils from the feathers. It is recommended to use a front-loading machine and avoid agitators, as they can damage the bag. To ensure all the soap residue is removed, you may need to run the machine multiple times without adding soap until the water runs clear.
After washing, dry the sleeping bag on a low heat setting. Adding clean tennis balls or sneakers to the dryer can help break up down clumps and re-fluff the bag. Alternatively, you can dry-clean the bag, but be sure to ask the dry cleaner about the type of solvent they use, as some can strip the natural oils from the down.

Manufacturing defects
In some cases, the cleaning step may be skipped or rushed, causing the down to rot earlier and smell worse. This can be challenging to fix, and simply airing out the bag may not be sufficient. Proper washing, refluffing, and thorough drying may be required, and even then, the smell may persist.
To avoid this issue, it is essential to purchase your down sleeping bag from a reputable manufacturer. Look for the RDS (Responsible Down Standard) mark, which indicates that the feathers and down come from animals that have not been subjected to unnecessary harm. This standard helps ensure that the down has been properly cleaned and prepared for use in sleeping bags.
Additionally, some sleeping bags may have a chemical odour due to the synthetic fabric used in their construction. This may not be a defect but rather an expected characteristic of the materials used.
If you encounter a smelly sleeping bag due to manufacturing defects, it is recommended to contact the manufacturer to discuss the issue and explore possible solutions or returns.

Cleaning and drying techniques
Firstly, it is important to note that most smells are caused by dirt and moisture spoiling. The smell indicates that the bag is damp or was packed damp. The dirt is usually confined to the shell, not the down. To prevent dirt buildup, consider using a sleeping bag liner, which acts as a barrier between your skin and the bag.
If your sleeping bag is darkened with grime or losing its fluffiness, it is time to give it a good wash. You can hand wash it in a bathtub, send it to a professional service, or use a commercial washer and dryer at a laundromat.
When handwashing, put the bag into its compression sack, fill the bathtub with enough water to submerge the sack, and then pull the sleeping bag out of the compression sack underwater. This stops you from having to fight the bag to get the air out. Be sure to rinse numerous times to ensure no detergent is left behind.
If you are using a machine, ensure it is a front-loading washer or a top-loading machine without an agitator. Use a gentle cycle with warm or cold water and an appropriate soap, such as a down-safe detergent. Only use a small amount of soap to avoid oversudsing. To ensure all soap residue is gone, rinse at least twice or run a second complete wash-and-rinse cycle without detergent.
When drying, use a commercial-size dryer if possible, as this allows the bag to fully loft and tumble. If you are using a home dryer, ensure it is on low heat to prevent damage to the fabric. You can also air dry the sleeping bag for 12 hours, then put it back in the dryer on "air dry" for 30 minutes. To speed up the drying process, roll the bag up in a few towels and press firmly to soak up additional water.
To reloft the bag, add two or three clean tennis balls or a lightweight pair of clean sneakers to the dryer.

Frequently asked questions
If your sleeping bag still smells bad after washing it, it might be because it wasn't dried properly, causing mould to develop. Try hanging it out in the sun for a few days to let it air out. If that doesn't work, you may need to send it to a professional cleaner.
If your sleeping bag is new and has a bad odour, it might be due to a manufacturing defect or poor cleaning during the manufacturing process. Some companies may try to mask this odour with chemicals. To avoid this, look for the RDS or Responsible Down Standard mark when buying a new down sleeping bag.
To prevent your down sleeping bag from smelling, make sure to keep it dry, store it properly, and practice good hygiene when using it. Avoid getting it wet, and always let it dry completely before packing it up. Regularly hang it out in the sun and air it out to prevent odours from building up.
