Store, lightly stuffed, in a large, breathable bag (included) or hang in a dry location. This keeps your gear fluffy when stored for extended periods and it's why we didn't store your gear in it's stuff sack. Make sure your gear is completely dry before storing it.
Spot clean or hand wash when possible. If machine washing, use a front-load washer only and set to a warm, gentle cycle. Wash down product by itself with a cleaner specifically designed for down (NikWax® Down Wash). Do not use liquid detergent, and do not bleach. Rinse thoroughly, but do not wring. Air dry flat. Shake to restore loft or throw in a dryer on a "no heat" setting with a clean tennis ball. Never dry clean.
