How to wash your down jacket: a complete guide

Washing your down jacket properly is essential to maintain its warmth, loft, and longevity.
A well-cared-for jacket can last for years, keeping you cosy through countless hikes and cold-weather adventures. However, many people make common mistakes—using the wrong detergent, skipping key prep steps, or drying incorrectly—that can damage the feathers and fabric, leading to clumps and reduced insulation. This guide walks you through every step to ensure your jacket stays clean, warm, and ready for the long haul.

Understanding your down jacket

Down jackets are made from lightweight, insulating materials—typically nylon or polyester shells filled with goose or duck down. The science behind down insulation lies in its ability to trap warm air in tiny pockets formed by the feathers, creating a high warmth-to-weight ratio. Proper care is crucial to preserve this loft and prevent damage to the delicate structure of the down.

Preparing your down jacket for washing

Before you wash your down jacket, preparation is key. Start by checking the care label for specific instructions. Remove any fur trims, bags, or detachable accessories, and close all zips, Velcro, and buttons. This helps prevent damage to the fabric and ensures a more effective clean.

Checking the care label

Always check the care label before washing. Look for symbols indicating water temperature (cold or warm), cycle type (gentle), and drying instructions (tumble or air dry). Understanding these symbols ensures your item is cared for correctly.
Removing accessories and closing fastenings
Detach any removable parts like hoods or fur trims and secure all fastenings. This prevents damage and keeps the jacket from snagging during the wash. Store accessories in a safe place—mesh bags work well for keeping everything together.
