How to wash a sleeping bag?

Even though washing a sleeping bag can seem like a difficult task, it’s crucial for preserving the quality and durability of your equipment.

A sleeping bag is an investment, and proper care can help ensure it lasts for years to come.

Everything you need to know about washing a sleeping bag, including preparation, selecting the best detergent, washing methods, and drying techniques, will be covered in this article.


There are a few things you should do to get ready before you start washing your sleeping bag.

First, check the care label on your sleeping bag. The label will provide important information about the materials and construction of your sleeping bag and any specific care instructions you should follow. If the care label is missing or illegible, check the manufacturer’s website for care instructions or contact them directly for advice.

Next, inspect your sleeping bag for any signs of damage. Look for tears, rips, or holes in the fabric or insulation. If you find any damage, repair it before washing your sleeping bag to prevent further damage during the washing process.

Finally, remove any loose debris from your sleeping bag. Shake it out and use a soft brush or cloth to remove any dirt or debris from the surface. Pay special attention to any areas that are particularly dirty, such as the foot box or hood.

Choosing the Right Detergent

Choosing the right detergent is crucial when washing a sleeping bag. You want to use a mild, non-detergent soap that is specifically designed for washing down or synthetic insulation. Regular detergents can strip the natural oils from down insulation, causing it to lose its loft and warmth. They can also leave behind residue that can irritate your skin or cause your sleeping bag to smell.

There are several specialized detergents on the market that are designed for washing sleeping bags. Nikwax Down Wash, Grangers Down Wash, and Gear Aid ReviveX Pro Cleaner are all popular options. These detergents are formulated to clean and revitalize insulation while preserving its loft and warmth.

If you have a synthetic sleeping bag, you can use a gentle laundry detergent. Look for a detergent that is free of dyes, fragrances, and fabric softeners. These additives can leave behind residue that can irritate your skin or cause your sleeping bag to smell.

Washing Techniques

It’s crucial to use a gentle touch and follow the manufacturer’s instructions when washing your sleeping bag.

Here are the steps you should follow:

Step 1: Fill a bathtub or large sink with cool water. Add the appropriate amount of detergent for your sleeping bag and agitate the water to create suds.

Step 2: Immerse your sleeping bag in the water and gently press it down to submerge it completely. Avoid wringing or twisting the sleeping bag, as this can damage the insulation.

Step 3: Let your sleeping bag soak for 15 to 20 minutes, or according to the manufacturer’s instructions.

Step 4: Drain the soapy water and rinse your sleeping bag with cool water. Gently press down on the sleeping bag to remove as much water as possible.

Step 5: Refill the tub or sink with clean water and repeat the rinsing process until all soap residue is removed.

Step 6: Squeeze out any excess water from your sleeping bag. Do not twist or wring it, as this can damage the insulation.

Drying Methods

Drying your sleeping bag properly is just as important as washing it. Improper drying can cause the insulation to clump together or even melt, ruining your sleeping bag.

Here are some tips for drying your sleeping bag:

Tip 1: Use a commercial dryer if possible. Most sleeping bags can be dried in a commercial dryer on low heat. Add a few clean tennis balls or dryer balls to help fluff up the insulation and prevent it from clumping together. Check the manufacturer’s instructions before using a dryer, as some sleeping bags may require air drying.

Tip 2: Air dries if necessary. If you don’t have access to a commercial dryer or your sleeping bag is not suitable for machine drying, you can air dry it instead. Hang your sleeping bag over a clothesline or lay it flat on a clean surface in a well-ventilated area. Fluff up the insulation periodically as it dries to prevent clumping.

Tip 3: Avoid direct sunlight and high heat. Direct sunlight and high heat can damage the fabric and insulation of your sleeping bag. Keep your sleeping bag out of direct sunlight and away from heat sources like radiators or heaters.

Tip 4: Be patient. Drying a sleeping bag can take several hours or even a day or two. Be patient and allow your sleeping bag to dry completely before storing it.


Even though washing a sleeping bag may seem difficult, with the right planning, detergent, washing methods, and drying techniques, it’s a straightforward process that can help your equipment last longer.

Remember to check the care label and manufacturer’s instructions, use a mild detergent, be gentle when washing and drying, and be patient while your sleeping bag dries. With these tips, your sleeping bag will be clean, fresh, and ready for your next adventure.
