Goose Down Fill
Using only the highest-quality goose down in all of our products, each lot of down is thoroughly tested at three stages of production for loftiness, moisture resistance and ability to regain loft after compression. The fill power of goose down is an indicator of two important features: the warmth-to-weight ratio and compressibility, both critical to the user's warmth comfort. True fill power is measured by placing one ounce of down graduated cylinder and measuring the volume the down occupies cubic inches. Our products are insulated with exclusive, high-fill-power down ranging from 550 fill to 950 fill, representing the highest-quality down commercially available.
