Fur Vs Down: Which Winter Coat Is Warmer?

Fur coats are considered one of the warmest insulators known to man, and they are widely used for winter wear. The warmth of a fur coat depends on the type of fur used, with certain fur types such as sheepskin or fox being exceptionally insulating. The warmth of a fur coat can also be affected by the way it is worn, with some sources claiming that wearing a fur coat inside out can increase its insulating effect. This is because the fur creates small gaps that trap warm air inside the coat, similar to the concept of double-glazed windows. On the other hand, down coats are made from synthetic materials like polyester, nylon, or fiberfill, which provide a good level of warmth but are generally considered less warm than real fur coats.

Fur coat vs down coat: which is warmer?

When it comes to choosing a winter coat, two of the warmest options available are fur coats and down coats. Both types of coats are known for their exceptional warmth and ability to protect against cold weather, but is one warmer than the other?

The Warmth of Fur Coats

Fur has long been recognised as one of the warmest natural insulators available. The fur creates small gaps that trap air inside the coat, which then warms up and creates a layer of warmth around the wearer. This principle is similar to double-glazed windows or insulated walls, where layers of air are used to prevent heat transfer. While synthetic materials such as polyester and nylon can provide a good level of warmth, they often fall short of the superior warmth and moisture-resistant qualities offered by natural fur. Fur coats made from certain types of animal fur, such as sheepskin or fox, are known for their exceptional insulating properties. For example, fox fur is often used in arctic conditions as it does not ice up or frost up in sub-zero temperatures.

The Warmth of Down Coats

Down coats, on the other hand, are filled with the soft inner feathers of ducks or geese, which create a layer of trapped air that helps to retain body heat and keep the wearer warm. Down is also known for its lightweight and compressible nature, making it a popular choice for those seeking a warm coat without the bulk. However, it is important to note that down may not be as effective as fur in extremely cold temperatures, as it can struggle to retain warmth when compressed or exposed to strong winds.

So, which type of coat is warmer? Both fur coats and down coats offer exceptional warmth and have their unique advantages. Fur coats, with their natural insulating properties, are ideal for those seeking a luxurious and extremely warm option. Down coats, meanwhile, provide a good balance of warmth and lightweight comfort, making them a versatile choice for various winter activities. Ultimately, the decision between a fur coat and a down coat may come down to personal preferences for style, weight, and other factors beyond just warmth.

The insulating properties of fur

Fur is one of the warmest insulators known, and it is widely used for winter wear. The insulating properties of fur are due to the small gaps created by the fur that trap air inside, which then warms up and keeps you warm. This is a similar concept to double-glazed windows or twin-brick houses, which work by creating an air gap.

When fur is worn with the fur on the inside, the space available for trapping air is reduced, making it less effective as an insulator. In contrast, when worn with the fur on the outside, the fur is open to the air and can trap more air, providing better insulation. Additionally, the fur acts as a wind-proof barrier, further enhancing its insulating properties.

Another factor that affects the insulating properties of fur is its ability to conform closely to the body. Insulators work best when they fit snugly, as any gap between the insulator and the skin can act as a chimney, convecting heat away from the body. Therefore, a well-fitting fur coat will provide better insulation than a loose-fitting one.

Overall, the insulating properties of fur make it an excellent choice for staying warm during cold winter months. Its ability to trap air and create a barrier against the wind make it a superior insulator compared to synthetic materials.

The effect of wind on the warmth of a fur coat

The effectiveness of a fur coat in providing warmth is influenced by various factors, one of which is wind. While fur is widely recognised for its exceptional insulating properties, the presence of wind can impact its performance.

The insulating capability of fur coats is attributed to the dense layers of fur that act as a barrier, impeding the transfer of heat from the body to the external environment. The hollow fibres in the fur are key to this process, as they trap air and prevent body heat from escaping. This trapped air creates a microclimate that shields the wearer from the cold.

However, wind can disrupt the insulating properties of fur by displacing the warm trapped air with cold air. This displacement of air can compromise the microclimate created by the fur, reducing its effectiveness in retaining warmth. The impact of wind on the warmth of a fur coat is similar to the effect it has on other insulating materials. When insulating materials are exposed to moving air, they continuously lose the warm air trapped within, resulting in a repeated cooling effect.

To mitigate the impact of wind, wearing the fur coat with the fur facing inward can be beneficial. In this configuration, the fur acts as a wind-proof barrier, providing better protection against the wind. Additionally, the fur may conform more closely to the body when worn inward, reducing convection effects that contribute to heat loss.

It is worth noting that different types of fur vary in thickness, density, and length, which can also influence their ability to retain warmth in windy conditions. Some fur types, such as fox fur, are known for their exceptional insulating properties and are less likely to be affected by wind. Overall, while wind can impact the warmth provided by a fur coat, the unique structure and insulating properties of fur still make it one of the warmest options available.

The best types of fur for warmth

Fur is one of the warmest insulators known, and it is highly used for winter wear. Some of the best types of fur for warmth include:

Fox

Fox fur is wonderfully fluffy and ideal for high-fashion trim on collars, cuffs, wraps, headbands, vests, jackets, and coats. Fox fur is also used in arctic conditions as it does not ice up or frost up in sub-zero temperatures.

Sheepskin, also known as shearling, is considered the most common type of fur and one of the most affordable. It is also incredibly durable.

Sable

A sable coat is made up of soft wool topped by a dense coat of fur, and then topped again by an even longer coat of hair, making it exceptionally warm and practical. Sable has been a status symbol throughout history, with Russian nobility coveting their skins.

Chinchilla

Chinchilla fur is one of the most expensive and luxurious of all fur types. Each follicle on a chinchilla's body produces 60 hairs, making the fur the densest of any land-dwelling mammal.

Beaver

Beaver fur is considered a premium fur and is often seen as very attractive to designers. It is slightly less durable than other furs but has a velvet-like texture and is very plush.

Coyote

Coyote fur is dense and durable, and, although coyotes are primarily seen as pest animals, they are perfect for practical garments. The long guard hairs are dark and long, making them suitable for parka ruffs similar to wolf fur.

Muskox

Although expensive, muskox wool (qiviut) is fine, soft, and warm.

Possum

Possum fur is one of the warmest furs in the world and has become a viable eco-fur option.

The weight of fur coats

The weight of a fur coat is an important factor to consider when purchasing one. While fur coats are known for their exceptional warmth, different types of fur vary in weight, with some being lighter and more suitable for summer wear, while others are heavier and ideal for winter. For instance, a full-length lynx coat has weight but is still lighter than a fox fur coat.

Fur coats are often perceived as heavy and bulky, but this is not always the case. In fact, many fur coats are surprisingly lightweight, defying the expectation that they are cumbersome to wear. This lightweight characteristic of fur coats is attributed to the presence of a dense, soft underfur beneath the glossy guard hairs, which contributes to their exceptional warmth without adding excessive weight.

The weight of a fur coat is influenced by several factors, including the type of animal fur used, the length of the coat, and the density of the fur. For example, fox fur is known for its long, lustrous guard hairs and soft, thick underfur, resulting in a fuller and slightly heavier coat. On the other hand, mink fur is noted for its lightweight characteristics, with female mink pelts being particularly lighter, softer, and more supple than male mink pelts.

When considering the weight of a fur coat, it's essential to remember that it should be balanced and fall evenly and comfortably from the shoulders. A well-made fur coat will have a certain "give" to the leather side when horizontal tension is applied, ensuring a comfortable fit. Additionally, the weight of the coat should be distributed evenly to avoid any discomfort or strain on the body.

Ultimately, the weight of a fur coat is a matter of personal preference and intended use. For those seeking a lighter option, fur accessories or lighter-weight fur coats made from certain types of fur can provide warmth without the bulk. Conversely, for those prioritizing maximum warmth, a heavier fur coat with a dense underfur and longer guard hairs may be the preferred choice.
