Care Instructions

This product is made with a technically advanced Downtek™ fill.

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: Where your bag sleeps when you’re not sleeping in it affects its lifespan. Before storing after a camping trip, avoid gnarly smells and damaged fill by making sure your gear is completely dry. Then, 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 of time.

Cleaning instructions: Keep your down sleeping bag in tip-top shape by spot cleaning or hand washing 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 stay away from 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. This product does not look good with a perm. Never dry clean.
