Learn the safest way to wash your down jacket, restore its loft, and keep it performing for years to come.
Why Washing Your Down Jacket Matters
A quality down jacket is one of the best investments for staying warm outdoors. Over time, dirt, sweat and body oils reduce the insulation's ability to trap heat, leaving your jacket feeling flat and less effective.
The good news? With the right products and a little patience, you can restore your jacket's performance at home.
What You'll Need
Before you begin, gather:
- Down-specific detergent (avoid normal laundry detergent)
- Washing machine
- Tumble dryer
- 3–4 clean tennis balls or dryer balls
- Clean towel
- Plenty of time
Step 1 – Check the Care Label
Always start by reading the manufacturer's washing instructions.
Most modern down jackets can be machine washed, but it's always worth checking first.
Step 2 – Prepare the Jacket
Before washing:
✓ Empty every pocket
✓ Zip up all zips
✓ Fasten Velcro tabs
✓ Loosen drawcords
✓ Brush away any mud
Step 3 – Use the Right Detergent
Never use:
❌ Biological detergent
❌ Fabric softener
❌ Bleach
These products strip the natural oils from the down and reduce its insulating ability.
Instead, use a specialist down wash designed specifically for insulated clothing.
Step 4 – Wash on a Gentle Cycle
Recommended settings:
- 30°C
- Gentle cycle
- Low spin (around 400–600 rpm)
If your washing machine offers an extra rinse, use it to remove any remaining detergent.
Step 5 – Dry It Properly
Drying is the most important step.
Place the jacket into a tumble dryer on low heat with 3–4 dryer balls or clean tennis balls.
These continually break up the clumps of wet down as the jacket dries.
Don't rush this process—it can take several hours.
How Do You Know It's Dry?
Your jacket should:
- Feel light and fluffy
- Have no cold or damp patches
- Regain its original loft
- Feel evenly insulated throughout
If you're unsure, continue drying.
Even a small amount of moisture left inside can cause the down to clump together.
Common Mistakes
Avoid these common errors:
- Using normal washing detergent
- Air drying without fluffing
- High tumble dryer temperatures
- Storing the jacket while damp
- Washing too frequently
When Should You Wash It?
For most hikers:
- Around 1–2 times per year
- Whenever the jacket starts losing loft
- After particularly dirty trips
- Before storing it for long periods
Looking After Your Jacket
To get the longest life from your jacket:
- Hang it rather than compressing it for storage
- Spot clean small marks where possible
- Store it somewhere dry and well ventilated
- Wash it using specialist down wash when needed
A little maintenance can add years to the life of a quality down jacket.
