How to Use

Upon unboxing, remove the comforter from its packaging and shake it vigorously to allow the compressed down clusters to regain their natural loft. For optimal results, let the comforter air out in a well-ventilated space for 3–4 hours before its first use. It is highly recommended to use this comforter with a duvet cover to protect the high-density fabric and prolong the life of the down.

Care & Safety

To maintain the integrity of the 5A down, store the comforter in a cool, dry, and breathable bag when not in use. Avoid heavy compression during storage, as this can damage the down filaments and reduce loftiness over time. Keep the comforter away from sharp objects to prevent punctures to the specialized anti-leakage fabric. If the comforter becomes damp, air-dry it thoroughly in a shaded, ventilated area; avoid direct high-heat exposure which can strip the natural oils from the down.
