How to Wash a Down Jacket Without Losing Loft

Down jackets are expensive and delicate -- but they need washing to maintain their warmth and loft. Dirt and body oils compress down clusters over time, reducing insulation. The good news: you can safely wash a down jacket at home or at the laundromat if you follow the right steps.

The key rules: use a front-load machine, cold water, down-specific detergent, and tumble dry with tennis balls. Here is the complete process.

How to Wash a Down Jacket in the Washing Machine

Check the care label -- Most down jackets are machine washable. If it says dry clean only, follow that instruction.
Close all zippers and Velcro -- Open zippers snag fabric. Velcro catches on everything.
Turn inside out -- Protects the outer shell fabric.
Use a front-load machine -- Top-loaders with agitators can tear baffles and damage down clusters. If you only have a top-loader, use a laundromat with front-load machines.
Use down-specific detergent -- Nikwax Down Wash, Granger Down Wash, or Gear Aid ReviveX. Regular detergent strips the natural oils from down and reduces loft. Never use fabric softener or bleach.
Wash on gentle/delicate with cold water
Run an extra rinse cycle -- Down traps soap easily. Residual detergent clumps the fill.

How to Dry a Down Jacket (The Critical Step)

Drying is more important than washing. Down must be completely dry to prevent mold and restore loft.

Tumble dry on LOW heat -- Not air dry, not high heat. Low heat gradually dries the down without damaging it.
Add 2-3 clean tennis balls or dryer balls -- They break up clumps of wet down as the jacket tumbles, restoring even loft distribution.
Expect it to take 2-3 hours -- Down takes much longer to dry than regular clothes. Do not rush it.
Check for damp spots -- Pull the jacket out periodically and feel for wet clumps. If you find any, keep drying.

Never hang dry a down jacket. The wet down clumps at the bottom of each baffle and dries unevenly, leaving you with a lumpy, poorly insulating jacket.

When to Use the Laundromat

Home machines are often too small for puffy down jackets. Laundromat machines offer the large drum capacity needed for the jacket to tumble freely. Their commercial dryers also run hotter and more evenly than home dryers, cutting dry time significantly. See our guide to washing bulky items at the laundromat.

Frequently Asked Questions

How often should I wash a down jacket?
Once or twice per season is enough for most people. Wash more frequently if you wear it daily or sweat heavily in it.

Can I dry clean a down jacket?
Some care labels say dry clean, but many outdoor gear experts advise against it. The solvents used in dry cleaning can strip the natural oils from down feathers, reducing insulation permanently.

My down jacket is clumpy after washing. Is it ruined?
No -- it just needs more drying time with tennis balls. Put it back in the dryer on low with dryer balls and run for another hour. The clumps will break up.
