BENEFITS
What Is Down?
Down is a natural insulator made up of soft clusters found beneath the outer feathers of waterfowl, such as ducks and geese.
Duck vs. Goose Down
Goose down clusters are typically larger and more resilient, providing greater loft, insulation, softness, and an exceptional warmth-to-weight ratio.
Natural Temperature Regulation
Down clusters trap warmth while remaining remarkably light and breathable, creating the airy comfort down is known for.
Excellent Warmth-to-Weight Ratio
Fill power measures a down's loft. Higher fill power indicates larger, more resilient clusters that deliver greater warmth and loft with less fill and bulk.
Soft, Adaptive Support
Down clusters compress and rebound naturally, creating responsive support that gently conforms while maintaining a soft, cushioned feel.
Longevity
With proper care, high-quality down can maintain its comfort, loft, and performance for years.
Responsible Sourcing
Down is a natural byproduct, and we ensure our down is responsibly sourced. As a natural material, it is biodegradable at the end of its lifespan.
Disclaimer
Products labeled as "down" typically contain a small percentage of feathers—up to 25% under industry standards. Please refer to the law label for your product's exact down and feather composition.
CARE
- Proper Protection: Extend the life of your insert and promote a cleaner sleep environment with a protective cover.
- Maintenance Matters: Spot or Dry Clean Recommended. Try New Zealand Wool Dryer Balls to help prevent clumping.
