The performance of this fill (heat retention!) is directly tied to its “loftiness." To help your products retain their loft, please follow our storage and cleaning instructions. Remember: Loft = warmth. Lofty gear = happy you.

Storage instructions: 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 is why your gear is currently not in the stuff sack. Make sure your gear is completely dry before storing it.

Cleaning instructions: 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 like 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.
