Down jackets, like any other form of clothing, can suffer from odors or stains. Yet, you should give washing and drying down-filled garments more consideration than when you wash your favorite sweatshirt. Each Marmot down jacket has a specific loft or thickness of down that not only provides insulation, but also gives the garment its shape. You can help retain the original loft of your jacket by using down-specific measures when you wash and dry it.
Place the jacket in your washing machine on a gentle cycle with a warm water wash and rinse. If you have a washing machine that offers you the option of setting a second rinse cycle, set it.
Add the manufacturer's recommended amount of down wash to the washing machine and allow the wash and rinse cycle to finish. If your washing machine performed a second rinse, skip to Step 4. If not, proceed to Step 3.
Turn the dial on your washing machine to the rinse cycle. Choose a warm water setting and allow the machine to rinse the jacket a second time.
Place the jacket in your clothes dryer on a low heat setting. Put two clean tennis balls in with the jacket to help it regain its loftiness as it dries.
Dry the jacket on low heat for approximately 2 to 3 hours. Check on the jacket every hour to turn it, if needed. Remove promptly when it's fully dry.
Down wash can often be found at camping and outdoors equipment stores.
Don't use regular detergent to wash your Marmot down jacket as it may leave a residue on the outer fabric.
Do not use any type of liquid or sheet fabric softener when washing or drying your down jacket.
