Why Do Down Jackets Keep You So Warm?
A down jacket is one of the best choices when it comes to winter attire. These jackets can typically stand up to subzero temperatures, allowing you to remain comfortable and protected from the cold.

Composition of Down Jackets
-
The outside of a down jacket is typically made of durable, water-repellent nylon. This type of lining insures that no water can penetrate and also keeps the wearer dry. The nylon is typically thicker around the shoulders and neck of the jacket. A down jacket is filled with goose feathers, which are very warm and are known to insulate heat very effectively.
Features of Down Jackets
-
Down jackets will typically include other amenities for warmth, aside from the down goose feathers and water-resistant lining. Many down jackets will have fleece-lined hand-warmer pockets along with inside and outside chest pockets. A down jacket has a draw cord at the bottom and the top of the jacket. These cords can be easily tightened to seal in heat. Down jackets also come with full-length zippers and a chin guard to further keep out the cold.
How Down Jackets Keep You Warm
-
A down jacket keeps you warm by storing warm air that has been created by the body in the insulation of the jacket. A person's body radiates heat, and the down feathers in the jacket will store the heat. This creates an oven-like effect inside the jacket. The drawstrings on the jacket further help prevent heat from escaping, and the jacket will continue to get warmer the longer you wear it. The more insulated the jacket is, the harder it is for heat to escape.
Benefits of Down Jackets
-
A down jacket is very beneficial for someone who lives in an area where there are freezing temperatures. These jackets are tested to withstand up to zero degrees, and can therefore ward off frostbite. Despite its extreme warmth, the jacket is still lightweight and won't weigh you down.
Perfect for the Great Outdoors
-
If you spend a good amount of time outside during the cold weather, you'll have a much more comfortable experience wearing a down jacket. It is useful against freezing wind, and thus is perfect if you like to sleigh ride, snow board or ski.
