Which is Warmer: Wool or Down Blanket?

When it comes to keeping cozy during the cold winter months, many people turn to blankets to stay warm. Two popular options are wool and down blankets, but which one is warmer? Let's explore the differences between these materials and determine which is the best option for keeping you feeling warm and snug.

1. Understanding Wool Blankets

Wool blankets are made from the hair of various animals such as sheep, alpacas, or llamas. The material is extremely durable and can last for many years with proper care. Wool is also water-resistant and naturally fire-retardant, making it a favorite for outdoor use like camping or picnicking.

In terms of warmth, wool blankets are known to be both insulating and breathable. They trap heat close to the body, but they also allow a sufficient amount of air circulation, so you don't get too hot or stuffy. Also, wool blankets come in varying weights and materials, so you can choose one that suits your preference and the climate in which you live.

2. The Allure of Down Blankets

Down blankets are made from the soft and fluffy plumage found on the underbelly of waterfowl such as ducks or geese. The material is insulative due to the down's ability to trap air, and it feels light and airy.

A down blanket offers excellent warmth to weight ratio, which is why they are popular for outdoor enthusiasts, who require warm, lightweight equipment to take on trips. Additionally, they are amazing for beds because they can trap heat near your body while still keeping you cool, and hence, can be used throughout the year.

3. Insulation Value

The insulation value of a blanket is a critical factor to consider when determining which is warmer: wool or down. Wool blankets typically have an insulation value of 3.7 to 4.3 per inch and tend to have a higher insulation value than down blankets.

However, the insulation value is harder to measure in down blankets because the fill power (which indicates the amount of air it can trap per cubic inch) ranges between 400 to 900 depending on the blanket's grade. Thus, determining the insulation value for down blankets is much more complex than wool.

4. Allergy Concerns

Wool and down both require animal-derived materials, so it's essential to consider any allergy concerns when choosing a blanket. Some people may have a mild or severe allergy to wool, while others are allergic to the natural lanolin present in the wool.

Meanwhile, a down blanket can be challenging for those allergic to feathers as the material can release dust and micro particles, causing significant respiratory distress. Therefore, choosing a blanket that suits your allergy needs and preferences is essential.

5. Durability

Another essential factor when it comes to choosing a warm and cozy blanket is durability. Wool blankets are naturally sturdier than down blankets as wool fibers are densely packed and more robust.

On the other hand, down blankets can be harder to protect and care for since they need careful washing and drying to preserve their insulation value and soft structure. If you live in a damp climate, a woolen blanket would be an excellent option to provide you with both warmth and durability.


In summary, both wool and down blankets are excellent choices for staying warm during winter. Wool blankets could be the better choice for those living in damp regions as they are more substantial than down blankets, and provide more warmth, and can withstand moisture. But if you are after a lighter and more versatile blanket, down will more than suit your needs. Ultimately, the choice boils down to personal preference, taking into account the environment, climate, and allergies that need addressing. Invest some time researching and finding the perfect blanket that provides the warmth and quality that you need and fits your tastes.
