For those who value gear that lasts, washing a down jacket is the moment of truth. Done right, the jacket comes out of the drum as warm as the day you bought it. Done wrong, the fill clumps into cold fists and no amount of shaking brings it back. The method below is the one we recommend for every Bergen parka, and it works for any quality down garment.
Before you start
Close every zipper and fastener, turn the jacket inside out, and empty the pockets — a forgotten coin will bruise both the drum and the jacket. Spot-clean the collar and cuffs first with a soft brush and diluted detergent; often that is all the jacket needs, and the less often you machine-wash down, the longer it lives.
1. Machine, not hands
Counter-intuitively, hand washing is harsher on down: you cannot rinse the fill evenly, and detergent left inside destroys loft. Use a front-loading machine, 30 °C, gentle or wool cycle, and the slowest spin available — 400 to 600 rpm.
2. The right detergent, and less of it
Ordinary powder strips the natural oils that make down springy. Use a liquid down-specific detergent, and use half of what the bottle suggests. Skip softener entirely — it coats the clusters and kills their loft permanently.
3. Rinse twice
Run a second rinse cycle. Residual detergent is the single most common reason a washed jacket loses warmth: it makes down absorb moisture instead of repelling it.
4. Dry with tennis balls — and patience
Tumble-dry on low heat with three clean tennis balls; they break up the wet clumps as the drum turns. Expect two to three cycles with breaks — down must be completely dry inside, which takes hours, not minutes. No dryer? Lay the jacket flat near (never on) a radiator and massage the clumps apart by hand every hour. If the fabric of your jacket says do not tumble dry — as on some of our shells with membrane treatments — the flat method is the safe one.
5. Wake the loft
Once fully dry, shake the jacket hard and pat every chamber so the clusters redistribute. The jacket should feel evenly plump, with no thin cold spots when held against a lamp.
What not to do
Never dry-clean down — the solvents strip its oils for good. Never store a parka compressed for the summer; hang it or keep it in a large breathable bag. And never wash more than once or twice a season: down cleans less often than it seems.
Treat the fill with respect and it repays you: our test parkas have crossed pack ice, been washed dozens of times, and still hold their rating. That is what equipment is supposed to do.
