Ounce for ounce there is nothing that insulates against the cold quite like goose down. North Face understands this and has created a line of women’s down jackets that help keep the cold of outdoor winter activities at bay.
Now onto the one item that makes The North Face women’s 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.
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.
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.
