How to care for down and synthetic jackets so they actually last
A quality insulated jacket is an investment—and it'll repay you with years of warmth if you treat it right. Here's exactly how to wash, dry, and store both down and synthetic jackets without destroying the loft.
5 min read · IrisDown and synthetic insulation are engineered to trap warm air, but they're also magnets for body oils, sweat, and dirt that compress the fibers and kill their performance. The good news: both materials are tougher than you think. With the right approach—gentle detergent, cool water, and proper drying—you can restore loft and extend your jacket's life by years.
The key difference between the two: down requires more delicate handling but responds beautifully to proper care, while synthetics are more forgiving but need consistent attention to prevent matting. Either way, the process is straightforward enough to do at home.

Step one · 5 minutes
Check the care label and spot-treat stains
Before anything else, read your jacket's care tag—some premium pieces have specific requirements. Spot-treat visible stains with a soft brush or cloth and a tiny amount of mild detergent mixed with cool water. Gently dab (never rub) the affected area and let it air-dry. This prevents you from over-washing the entire jacket when only one section needs attention. For grease stains, a drop of dish soap on a damp cloth works surprisingly well.
Don't use bleach, fabric softener, or enzyme-based detergents—they damage both down and synthetic fibers.
Step two · 10 minutes
Hand-wash or use the gentle machine cycle
Fill a bathtub or large sink with cool water (never hot—it damages insulation). Add a small amount of down-specific or wool-friendly detergent; regular laundry detergent is too harsh. Submerge the jacket and gently agitate it for 2–3 minutes, paying attention to cuffs, collar, and underarms where sweat accumulates. For synthetic jackets, you can use a washing machine on the delicate cycle with cold water, but hand-washing gives you more control and extends the jacket's life. Rinse thoroughly with cool water until no soap remains—residue traps moisture and reduces breathability.
Never wring or twist your jacket. Instead, gently squeeze soapy water through the fabric.
Step three · 5 minutes
Remove excess water without damaging the fill
Lay the wet jacket flat on a clean towel. Roll the towel tightly around the jacket to absorb water—don't squeeze or compress it heavily. Unroll and repeat with a second dry towel if needed. This method removes moisture while keeping the insulation intact. Avoid the temptation to hang a soaking-wet jacket; the weight of the water can permanently damage the fill structure and create cold spots.
If you're in a hurry, gently press the jacket between your palms to push water out, then move to the drying step.
Step four · 20 minutes
Machine-dry on low heat with dryer balls
Place the damp jacket in a dryer on the lowest heat setting (or air-dry if your dryer has that option). Add 2–3 wool dryer balls or clean tennis balls to help fluff the insulation and prevent clumping. Run the dryer for 20–30 minutes, then check the jacket. It should feel dry to the touch but not hot. For down jackets especially, this tumbling action is crucial—it re-distributes the fill and restores loft. If your jacket still feels damp, run another 10-minute cycle. Never use high heat; it can melt synthetic fibers and damage down's structure.
Stop the dryer halfway through and give the jacket a gentle shake to redistribute the fill evenly.
Step five · 5 minutes
Store flat or loosely hung in a cool, dry place
Once completely dry, store your jacket flat or draped loosely over a hanger in a closet away from direct sunlight and heat sources. Never compress it into a vacuum bag for long-term storage—this permanently crushes the insulation and kills its warmth. If you must store it compressed, limit it to a few weeks. A breathable garment bag is ideal for protecting it from dust while allowing air circulation. Check on it occasionally during off-season storage to ensure no moisture has accumulated.
Hang your jacket in a well-ventilated closet, not in a plastic dry-cleaning bag, which traps moisture.

Refresh between washes with air and gentle brushing
You don't need to wash your jacket every season. Between washes, hang it outside on a breezy day for 1–2 hours to air out odors and moisture. Use a soft brush to gently remove surface dirt and restore texture. This simple maintenance extends the time between full washes and keeps your jacket fresher longer. If you notice any pilling on synthetic jackets, use a fabric comb or gentle lint roller to smooth it out.
Fresh air is your jacket's best friend—a monthly airing keeps it performing without the stress of frequent washing.
How to know your jacket is properly cared for
A well-maintained insulated jacket feels lofty and warm, with no cold spots or compressed areas. The fabric should be clean, the seams intact, and the insulation evenly distributed throughout. If your jacket passes these checks, you've done it right.
Questions at the mirror.
Can I dry-clean my down or synthetic jacket?
Avoid dry-cleaning if possible. The harsh chemicals and heat can damage insulation and degrade water-resistant coatings. Home washing is gentler and more effective. Reserve dry-cleaning only for jackets with special finishes or embellishments you're unsure about.
What if my jacket still feels damp after drying?
Run another 10–15 minute dryer cycle on low heat with dryer balls. Down jackets especially can take longer to fully dry because moisture gets trapped deep in the clusters. If it's still damp, lay it flat in a warm, dry room for 24 hours.
Is it normal for down to clump after washing?
Yes, but it should redistribute during drying. If clumping persists after multiple dryer cycles, gently massage the jacket by hand to break up clusters, then dry again. Persistent clumping suggests the down may have shifted due to a seam issue—consider professional repair.
How often should I wash my jacket?
Every 1–2 seasons for regular wear, or as needed if visibly dirty. Over-washing breaks down insulation faster than under-washing. Air and spot-treat between full washes to extend the interval.
