The Science: 18x Better for the Earth

To clear the air, the International Down and Feather Bureau (IDFB) commissioned a Life Cycle Assessment (LCA) to see how down stacks up against polyester. The results? Down has 1/18th the impact on climate change compared to polyester.

Choosing a synthetic comforter is effectively 18 times worse for the environment. Across human health, ecosystems, and energy use, down outperformed synthetics by a staggering 85% to 97%.

Comparison Analysis of Down and Polyester Filling Materials

A Sustainable Choice for International Day of Clean Energy

As we observe International Day of Clean Energy on January 26, the focus is often on solar or wind power. But true sustainability also means choosing materials that reduce our reliance on fossil fuels.

This is where down shines:

Renewable vs. Petroleum: Synthetics are born in oil refineries. Down is a natural by-product of the food industry that is saved and repurposed.
Energy-Saving: Down is nature’s best insulator. A high-quality comforter allows you to lower your thermostat at night, cutting your heating bills and saving energy.
Biodegradable: Unlike polyester "plastic" fillers that sit in landfills for centuries, down returns to the earth naturally.

The Bottom Line

FAQ

How do I choose the right fill weight for a down comforter?

It depends on your sleeping environment. We generally offer three options: Lightweight (for summer or warm sleepers), All-Season (our most popular versatile choice), and Ultra-Warm (for cold climates). We recommend an All-Season weight if your bedroom temperature is kept between -5-15°C (23-59°F).

What is Fill Power and why does it matter?

Fill Power (FP) measures the "loft" or fluffiness of the down. A higher Fill Power (such as 650+ or 750+) means the down can trap more air and provide more warmth with less weight, making the comforter feel incredibly light yet insulating.

Is the down comforter machine washable? How often should I clean it?

Yes, it is. However, we recommend washing it only every 2-3 years to preserve the natural down clusters. Always use a Duvet Cover to keep it clean. For washing, use a large-capacity machine with warm water on a gentle cycle. The key is to ensure it is completely dry to prevent clumping and odors.

What should I do if my new comforter has a slight odor or looks flat?

This is normal due to vacuum packaging for shipping. Simply remove it from the package, shake it gently, and allow it to air out in a well-ventilated area for 24-48 hours. It will naturally regain its full loft and any scent will dissipate.

What is the difference between Goose Down and Duck Down?

Goose down generally has larger clusters and higher Fill Power. Because geese are herbivores, goose down typically has less natural odor than duck down. For those seeking the ultimate lightweight experience or those with sensitive noses, Goose Down is the premium choice.

Can people with allergies use down comforters?

Yes. Our comforters undergo a rigorous hypoallergenic treatment and feature high-thread-count, down-proof fabric that acts as a barrier against dust mites and allergens.

Why does my down comforter always slide to the corner of the duvet cover?

This happens when there is no secure attachment. Our down comforters are designed with 8 sewn-in corner ties (or loops) that fasten securely to your duvet cover, ensuring the insert stays perfectly in place even if you toss and turn at night.
