What is the difference between down and feathers?
The feathers on geese or ducks are the outer covering of the bird. They have quills, repel water, and make it possible for the animal to fly. Down lies beneath this protective covering – usually on the belly of a bird - and is light and fluffy. It provides the insulation birds need to keep warm.
For example, one ounce of 800 fill-power down will occupy 800 cubic inches when compressed by a standardized weight. If you use two ounces of 800 fill on jacket A, and two ounces of 700 fill on jacket B, jacket A — with the 800 fill down — will be warmer because it has more loft.
- Waterproof Construction. Because water can impair insulation performance, especially in untreated down, the outer shell of an insulated jacket is water resistant. Some insulated shells go further, having a waterproof/breathable exterior fabric, along with taped seams.
- When selecting a feather & down product, it is important to note that there is a significant warmth difference between goose down and duck down. Geese are larger birds than ducks and generally have bigger down clusters. Their filaments are therefore able to trap more air and provide more insulation.
- Here's how to wash your down jacket at home:
- Find a front-loading washing machine; the agitator of a top-loader can damage down feathers.
- Set the dial to cold water, and add a touch of a down specific cleaner.
- After the wash cycle, make sure the jacket gets a thorough rinse; maybe set it for an extra cycle.
A down jacket is a jacket which has been insulated with the soft and warm under feathers from duck or geese. Goose down is often regarded as the warmest and lightest but duck down jackets, or jackets with a combination, are often cheaper.
- "Down fibre" means detached barbs from down and plumules or from the basal end of a feather quill shaft that are indistinguishable from the barbs of down. "Residue" means quill pith, feather fragments, trash and foreign matter. "Landfowl plumage" means the plumage of chickens, turkeys or other landfowl.
- Heatseeker™ The North Face uses this proprietary synthetic insulation in many of its jackets and pants. Thinsulate® A trademark of the 3M Corporation, Thinsulate® claims that its dense structure of very thin (~ 15 micrometers) fibers provides warmth without thickness.
- Billboard Advertising Costs. In my home city of Boston (Go Sox!), bulletins range from $11,000 - $23,000 per 4 weeks. In sunny San Diego, bulletins range from $8,400 - $15,000 per 4 weeks. In Midwestern Milwaukee, bulletins range from $3,000 - $4,000 per 4 weeks.
A down jacket is a jacket which has been insulated with the soft and warm under feathers from duck or geese. Down is a fantastic insulator as the loft (or fluffiness) of down creates thousands of tiny air pockets which trap warm air and retain heat, thus keeping the wearer very warm.

- The Most Versatile Jacket Yet: Packable Down. These jackets are lightweight yet warm . . . they feel like a cardigan but keep you warm like a down jacket. They're highly compressible and thin enough to layer under another jacket (Shana wears hers under her ski jacket) or tie around your waist.
- If you've noticed that your down gear is soaking up water or losing its water-repelling performance, try washing it first. The easiest way to waterproof a down jacket (or other down-insulated gear) is with a special wash or spray that's developed specifically for waterproofing technical fabrics and down-insulated gear.
