Goose Down Fills
Using only the highest quality Hungarian 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: warmth-to-weight ratio and compressibility; both critical to retain warmth and furnish comfort. 900 Fill Down: Highest quality, lightest, most compressible down commercially available and exclusive to The North Face. One ounce of this down fills a volume of 900 cubic inches - the highest weight to volume down available.
800+ Fill Down: Outstanding warmth in a lightweight package
700 Fill Down: Superior insulation in a lightweight for bitterly cold environments
600 Fill Down: Strong warmth-to-weight ratio for a range of temperatures
550 Fill Down: Lightweight insulation with a high weight-to-warmth ratio.
The North Face® innovative vaulted footbox provides sufficient space to allow the feet to flex and move naturally. This eliminates dead air space and keeps feet warmer and more comfortable.
