Goose Down Insulation
The North Face uses only the highest quality goose down in all of its 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 per of goose down is an indicator of two important fetters: the warmth-to -weight ratio and compressibility, both critical tot he user's warmth and comfort True fill power is measured by placing on ounce of down in a graduated cylinder and measuring the volume the down occupies ion cubic inches. The North Face products are insulated with exclusive, high-fill-power down ranging form 550 fill to 900 fill, which represents the highest quality down commercially available.
Water Resistant Down
Down is the warmest, lightest and most compressible insulation available, but when it gets wet, down clumps, stops insulating and takes a long time to dry. Water resistant down is a natural down insulation enhanced with a hydrophobic finish that keeps the down plumes from becoming saturated with moisutre and losing their insulation value. Water resistant down stays drier longer and dries faster than untreated down, improving its performance and versatility in a wider range of weather conditions.
Responsible Down Standard
Certified to the Responsible Down Standard (RDS) by Control Union. The RDS ensures that our down does not come from animals that have been subject to any unnecessary harm, such as force-feeding or live-plucking, and helps track the down used in our products from farm to finished garment.
