Yes, you can machine-wash a down jacket if its care label allows it.

Many down jackets can be machine-washed, but the care label on the specific jacket comes first. Patagonia recommends a front-loading washer where possible, a detergent made for down, and low-heat drying until the jacket is completely dry.

Before washing

Read the garment's care label and check for instructions that differ from general brand guidance. Empty the pockets and close zippers and fasteners. Use a clean machine so detergent or fabric softener from a previous load does not remain in the drum.

Patagonia advises using a down-specific detergent and avoiding bleach and fabric softener. A front-loader is preferred. If using a top-loader, select hand-wash or delicate only if the garment label permits it.

Drying takes time

Patagonia recommends low-heat drying for its down garments. Down can remain damp inside even when the shell feels dry, so continue drying until the insulation is fully dry and no longer clumped. Clean tennis balls or a clean towel can help separate clumps during drying, according to Patagonia's care guidance.

Do not use high heat or assume line drying is appropriate for every jacket. If the care label prohibits machine drying, follow the label. If the jacket's construction, trim, or care instructions are unclear, ask the manufacturer before washing.

Scope

These steps summarize Patagonia's general guidance, not a universal rule for every down garment. The sewn-in label for your jacket takes priority.
