While it’s tempting to want to save space and squeeze your down garments into the smallest bundle you possibly can, with continued compression the down can become more resistant to re-lofting (reducing the down’s effectiveness). While many down jackets and vests come with a compression sack, it’s best to use them as a short term travel quick-fix rather than a long term storage solution. Keep your down jackets and vests balled up for as little time as possible and away from long term vacuum sealed plastic storage bags.Best case scenario: After washing and letting them dry completely, store either on a hanger or folded loosely in a breathable cotton/canvas/mesh bag (a large cotton pillow case can do the trick). Ideally, you’ll want a storage space that is opened occasionally for regular airflow. The cool damp basement is not your friend. Try and keep them dry, away from any humidity, and make sure to never store them away wet or damp - Clothing put away wet is a recipe for mildew and rot.When you’re ready to pull your garments back out for the next season, toss them into the dryer and tumble dry on low for 10 minutes to give them that newly fluffed up feel. A high quality down garment is a worthwhile investment, and with these few simple steps to clean and store them properly, you can keep your down warm and fluffy for years to come.
