100% Cotton Shell - Soft, Breathable & Down-Proof

Wrapped in a 400 thread count 100% cotton shell, this comforter feels luxuriously soft, breathable, and moisture-wicking. The tight weave prevents down leakage while allowing airflow for a cool, dry, and comfortable night’s sleep.

Premium 800 Fill Power - Warmth Without the Weight

This comforter is filled with 90% white down at an impressive 800 fill power, delivering exceptional warmth without bulk. High fill power means larger, loftier clusters that trap more air, so you stay cozy with fewer ounces—and less weight on your body. The natural breathability of down helps regulate temperature and wick moisture for comfortable sleep across changing seasons.

800 Fill Power: Bigger Down Clusters, More Warmth with Less Weight

Three white clusters labeled 600, 700, and 800 fill power, increasing in size from left to right on black background.

What is Fill Power

Fill power is a measure of down quality, expressed as the number of cubic inches one ounce of down can loft. The higher the fill power, the bigger the down clusters, which means more warmth with less weight and a softer, loftier feel.

Lighter, Warmer, Airier

800 fill power down uses larger, higher-quality clusters. Because each cluster traps more air, you need less down overall to achieve the same insulation. That means the comforter feels billowy and light, not heavy or bulky.

Naturally Breathable & Lasting Loft

800 fill power down is naturally breathable, allowing air to circulate so you stay warm without overheating. Its larger, stronger clusters also hold their shape longer, giving your comforter a lasting loft

FAQ

Are down and feathers in this down comforter ethically sourced?

Yes, the down and feathers in this comforter are certified by the Responsible Down Standard (RDS). This voluntary global certification ensures that the materials are sourced from animals that have been treated humanely and not subjected to unnecessary harm.

How often should I wash my down comforter?

Down comforters require minimal washing—typically just once or twice a year. Using a comforter cover helps keep it clean and extends the time between washes.

How do I choose the right size down comforter for my bed?

Start by measuring the width and length of your mattress. Comforters are typically sized to match standard mattress dimensions—twin, full, queen, king, and California king. For the best coverage and a more luxurious drape, consider choosing a comforter that matches or slightly exceeds your mattress size.

Why does my down bedding have a scent?

A faint scent is natural and comes from the essential oils in down that help keep it soft and resilient. Even high-quality, clean down may have a mild odor—especially noticeable to those with a sensitive sense of smell. Heat, humidity, or prolonged moisture exposure can make the scent more noticeable.

To reduce or eliminate the smell, air out your down bedding in the sun for a few hours or tumble dry it on low heat until fully dry. Proper drying also helps prevent mildew.
