Zipped to prevent the zipper from catching on the drum or other parts of the bag

Whether you should wash your sleeping bag zipped or unzipped depends on the manufacturer's instructions and the design of the bag. Some manufacturers recommend washing the sleeping bag partially zipped up to prevent the zipper from catching on the drum or other parts of the bag. This is because the slider can get snagged or broken during the wash cycle, which can also cause damage to the stitching and displace the loft.

If you are using a front-loading washer, it is recommended to unzip the bag completely. This is because the agitators in top-loading washers can damage the bag and cause the bag to become entangled or wrapped around the agitator column.

It is important to follow the specific guidance provided by the sleeping bag manufacturer to avoid any damage during washing. For example, some bags may need to be washed by hand or with a specific type of detergent. It is also a good idea to check the seams, zippers, and drawcords of your bag periodically to ensure they are in good condition.

Unzipped to ensure a thorough clean and prevent stress on the zipper

It is important to wash your sleeping bag to extend its life and improve its performance. The process of washing a sleeping bag can vary depending on the manufacturer's instructions and the design of the bag. Some manufacturers recommend washing the sleeping bag partially zipped to prevent the zipper from catching on the drum or other parts of the bag.

However, to ensure a thorough clean and prevent stress on the zipper, it is advisable to completely unzip the bag. This is especially important if you are using a commercial washer and dryer or a front-loading machine, as the slider can snag or break, potentially damaging the zipper. A completely unzipped bag allows for better rinsing and ensures that cleaning agent residue does not collect inside.

When washing your sleeping bag, it is recommended to use a mild, non-detergent soap specifically designed for sleeping bags. Wash on a gentle cycle with warm or cold water to protect the bag's insulation and fabric. Avoid using standard laundry detergent, as the fillers and brighteners can stick to the bag's fabric and reduce its loft. For down bags, consider using a gear wash formulated for down, such as Nikwax Down Wash Direct.

After washing, it is crucial to ensure that the sleeping bag is thoroughly dried before storing it. Synthetic bags can be tumble-dried on low heat, while down bags are typically air-dried. To speed up the drying process, you can add a few tennis balls to the dryer or lay the bag flat in an area with low humidity and no direct sunlight.

Additionally, it is worth noting that washing your sleeping bag can be labour-intensive, and professional cleaning services are available if needed. Regular spot cleaning and following the manufacturer's care instructions can also help maintain your sleeping bag between washes.

Hand washing a sleeping bag

For down bags, use a cleaner that's specifically formulated for down, like Nikwax Down Wash Direct, or one that states it's safe for use on down items. Standard laundry detergent can lead to clumping or reduced loft. For synthetic bags, a technical cleaner like Nikwax's Tech-Wash is recommended.

Once the bag is cleaned, gently squeeze out the excess water and proceed to the drying step. It is important to never pick up a down sleeping bag when it is full of water. The weight of the water may tear out the internal baffles or cause the down to shift or 'migrate' from one chamber to another. For synthetic bags, picking up the bag when it is full of water may tear the stitching which anchors the insulation.

Synthetic sleeping bags will dry a lot quicker than down sleeping bags. Expect a synthetic bag to take at least an hour; a down bag will take several hours to dry thoroughly. You can also air dry your bag by laying it flat on a clean surface in an area with low humidity and no direct sunlight. Or you can hang it up to dry, being careful to distribute the weight so as not to put too much stress on the nylon fabric.

Using a commercial washer

When using a commercial washer to clean your sleeping bag, there are several steps you can take to ensure a thorough and safe wash. Firstly, it is recommended to use a front-loading commercial washer at a laundromat. The larger capacity ensures your bag will be rinsed and cleaned thoroughly. If you use a top-loading washer with an agitator column, your sleeping bag may become entangled and damaged.

When preparing your sleeping bag for washing, it is generally recommended to unzip the bag completely to prevent the slider from snagging or breaking. However, some sources suggest zipping up the bag to prevent damage to the zipper and from the zipper to the machine. If you do decide to zip the bag, be sure to check the manufacturer's instructions first, as some sleeping bags may require being unzipped.

When washing your sleeping bag, use a technical cleaner designed for sleeping bags, such as Nikwax Tech Wash, or a gear wash specifically formulated for down bags, like Nikwax Down Wash Direct. Avoid using standard laundry detergent, as it can lead to clumping, reduced loft, or leave a film that affects the bag's performance. Wash your sleeping bag in warm or cool water, on a gentle cycle, following the bag maker's instructions. To ensure all cleaning agents are removed, rinse the bag at least twice, or run it through an additional complete wash-and-rinse cycle without detergent.

After the wash cycle is complete, gently squeeze out any excess water before transferring the bag to the dryer. It is important to remove as much water as possible from the bag before drying, as the weight of the water can cause damage to the bag's internal structure. Set the dryer to low heat, as high temperatures can melt the delicate nylon and synthetic fabrics of your sleeping bag.

Drying a sleeping bag

Drying Methods

There are several methods for drying a sleeping bag, each with its own advantages and considerations:

  • Machine Drying: Using a commercial dryer at a laundromat is recommended for its large capacity and controlled settings. Set the dryer to low heat to avoid damaging the delicate fabric. If possible, tumble dry the bag, as the tumbling action helps to restore the loft by breaking up clumps of down or synthetic fill.
  • Air Drying: If a dryer is unavailable, you can air dry your sleeping bag. Lay it flat on a clean surface in an area with low humidity and no direct sunlight. Alternatively, you can hang it up to dry, but be cautious not to put too much stress on the nylon fabric. Air drying may take a couple of days, so ensure the bag is thoroughly dry before storing it to prevent mildew.

Precautions and Tips

  • Always ensure your sleeping bag is completely rinsed of any cleaning agents or soap before drying.
  • When removing the bag from the washer, support its entire weight to avoid straining and ripping the seams.
  • Gently squeeze out excess water before placing the bag in the dryer or hanging it up to dry.
  • For down sleeping bags, add two to three tennis balls or rolled-up socks to the dryer. This helps restore the loft by breaking up clumps and speeding up the drying process. Tennis balls are optional for synthetic bags.
  • If using a home dryer, be cautious not to use high heat, as it can melt the delicate nylon fabric.
  • Before storing your sleeping bag, ensure it is entirely dry. You can lay it out or hang it up overnight to be certain.
  • Avoid dry cleaning your sleeping bag, as the solvents can strip the natural oils from the down, impacting its loft.
  • Avoid using fabric softener, bleach, or alternative bleach products when washing your sleeping bag.
