Ounce for ounce there is nothing that insulates against the cold quite like goose down. The North Face understands this and has created a line of womens down jackets that help keep the cold of outdoor winter activities at bay. And with 40 years of outdoor gear design and testing experience you know you are getting a quality product that is durable and will stand up to whatever you throw at it.
Now onto the one item that makes The North Face womens down jacket such a toasty coat; the down. Hungarian goose down is use exclusively in all their down products and before it can be used it must pass three different tests. Loft, moisture resistance, and ability to regain loft after compression are all tested and only the down that passes is used in a their down jackets.
Fill power is the measure of the warmth-to-weight ratio and compressibility. These two measures are what give goose down it great insulating ability. To measure fill power an ounce of down is placed in a graduated cylinder and the volume of space it occupies is then measured. Goose down in the 550 to 900 fill power range is what they are looking for to use in all their down products.
550 Fill Down has a high weight-to-warmth ratio and is used primarily as a light weight insulator.
600 Fill Down is a good insulator over a good range of temperature conditions.
700 Fill Down is a lightweight insulator that works well in extreme cold conditions.
800+ Fill Down provides an outstanding insulating ratio because of its high cluster to feather ratio. It also has a high loft and compressibility factor that the lesser downs cannot match.
900 Fill Down is used exclusively by The North Face and is the highest quality goose down on the market today. It is highly compressible and boasts the highest warmth-to-weight ratio.
The Achilles heel of down is moisture; if it gets wet it loses its loft and its insulating ability. The North Face applies its Durable Water Resistant (DWR) finish to the outer fabric covering and zippers of it down jackets to create jackets that are water resistant and maintain their insulating ability.
For the active outdoor woman who loves the winter months it’s hard to beat the warmth, comfort, and durability of a North Face womens down jacket.
