Quick answer

Wash your down jacket in a front-loading machine on a gentle cycle with a small amount of down-specific detergent, then dry it on low heat with dryer balls until it is completely dry. Never use fabric softener, bleach, or a top-loading agitator, and never store the jacket compressed for long periods.

Down jackets are built to trap warm air in fluffy clusters, but that loft disappears when dirt, sweat, and body oils coat the feathers. A jacket that looks clean can still be losing warmth because the down has clumped and stopped expanding. Washing it correctly restores the loft and extends the life of the jacket.

Most down damage comes from good intentions: too much detergent, the wrong machine, or a half-dry jacket stuffed back into a closet. This guide walks through the full process, from spot cleaning to storage, with the checkpoints that keep you from making things worse.

Why down jackets need washing at all

Down insulation works by trapping air between feather clusters. When oils from your skin, sweat, and everyday grime coat those clusters, they stick together and stop trapping air. The jacket feels flat and cold even though nothing is torn. Washing removes the residue and lets the down rebound.

You do not need to wash a down jacket after every trip. Spot clean small marks and air the jacket between wears. A full wash is usually needed once or twice a season, or whenever the jacket looks dull, smells, or feels less puffy than it used to.

  • Check the care label first. Some shells have membranes or finishes that need specific treatment.
  • If the jacket has a waterproof coating, confirm whether the manufacturer recommends a technical wash before you proceed.

What you need before you start

Use a down-specific detergent or a mild, residue-free technical wash. Regular laundry detergent leaves behind surfactants that strip the natural oils from feathers and can leave a film that attracts more dirt. Fabric softener is worse: it coats the down and kills loft.

You also need a front-loading washing machine, or a bathtub if you do not have one. Top-loading machines with a central agitator can tear baffles and tangle the jacket. Dryer balls or clean tennis balls help break up clumps during drying.

  • Never use bleach, fabric softener, or dryer sheets on a down jacket.
  • Zip all zippers and close all flaps before washing to prevent snags.

Step-by-step: how to wash a down jacket

Start by emptying every pocket and closing all zippers, Velcro tabs, and flaps. Pretreat visible stains with a small amount of down detergent and a soft brush, then let it sit for a few minutes. This step matters because the wash cycle alone often will not lift set-in grime.

Place the jacket alone in a front-loading machine on a gentle or hand-wash cycle with cool water. Add the recommended amount of down detergent. Run an extra rinse cycle if your machine allows it, because leftover soap is one of the most common reasons down stays flat after washing.

  • Do not wash a down jacket with other clothing. The jacket needs room to move.
  • If you use a bathtub, press the jacket gently under the water instead of scrubbing it.

Drying: the step most people rush

Down clumps when wet, and it stays clumped if you let it air dry. Tumble dry on low heat with two or three dryer balls. Check the jacket every 20 to 30 minutes, pulling apart any clumps you find by hand. This can take several cycles, and that is normal.

The jacket is done when it feels completely dry, looks evenly puffy, and makes a light, crisp sound when you shake it. If it still feels cool or heavy in spots, keep drying. Storing a damp down jacket invites mildew and permanent clumping.

  • Never dry a down jacket on high heat. High heat can damage the shell and the down.
  • If you do not have a dryer, air dry in a warm, dry room and break up clumps by hand as it dries.

Storage and ongoing maintenance

Store your down jacket loosely on a hanger or in a large cotton storage bag. Compression is for travel, not for months in a closet. If you keep the jacket stuffed in a small sack, the down loses its ability to rebound over time.

Between washes, air the jacket after each use and spot clean marks with a damp cloth. For a jacket like the M's Bouncer Jacket, which uses PrimaLoft® Rise insulation, the same gentle approach applies: avoid harsh detergents and high heat so the insulation keeps its structure.

  • Hang the jacket to dry completely before storing it for the season.
  • Check seams and baffles once a year for loose threads or down leaks.

Down jacket care steps at a glance

  1. 1. Read the care label and check pockets: Confirm the jacket is machine washable and note any special instructions. Empty every pocket and close all zippers and flaps. Checkpoint: if the label says dry clean only, stop here and follow that instruction.
  2. 2. Pretreat stains and use down detergent: Apply a small amount of down-specific detergent to visible marks and let it sit for a few minutes. Never use fabric softener or bleach. Common mistake: using regular detergent, which leaves residue that flattens the down.
  3. 3. Wash alone on a gentle cycle: Use a front-loading machine on a gentle or hand-wash cycle with cool water. Add an extra rinse if possible. Checkpoint: if you only have a top-loader with an agitator, hand wash in a bathtub instead.
  4. 4. Tumble dry low with dryer balls: Dry on low heat with two or three dryer balls. Stop every 20 to 30 minutes to break up clumps by hand. Common mistake: pulling the jacket out while it is still damp, which leads to mildew and permanent clumping.
  5. 5. Store loosely, never compressed: Hang the jacket or store it in a large cotton bag. Keep it away from damp basements and direct sunlight. Next step: air the jacket after each wear and spot clean between full washes.

Product care notes from our catalog

  • M's Bouncer Jacket: This jacket uses PrimaLoft® Rise insulation, a synthetic fill that provides warmth with minimal weight. Synthetic fills like PrimaLoft® Rise still benefit from gentle washing and low-heat drying, but they tend to dry faster than natural down and are less prone to clumping.
  • Baby Alto Burrito: Made from Woolly Treemerino™, a stretchy, lightweight fabric that is 60% merino wool. Merino wool blends need cool water and mild detergent, so if you are caring for a wool garment alongside a down jacket, keep the wash temperatures and products separate.

Washing a down jacket is not complicated, but it is unforgiving of shortcuts. Use the right detergent, dry it completely, and store it loosely, and the jacket will keep its loft and warmth for many seasons.
