Isn't Wool Hot? Why Is It So Good For Temperature and Moisture?

Not at all — the unique and natural properties of wool make it an excellent temperature moderator.

People wear clothing made of wool to keep warm in cold climates, and people wear it to stay cool in hot desert areas. Just ask the Bedouins of the Middle East, who have been wearing wool in the middle of the desert for centuries.

For hundreds of years, these nomadic people have chosen wool for their treks across some of the hottest lands on Earth. That's because wool is well-known for its superior insulation properties, but only some people realize it works both ways.

The fact is: wool is an excellent temperature moderator, ideally suited for use in bedding. It's also sustainable, natural, and biodegradable. Wool will outperform most synthetic fibers due to its unique "crimped" structure.

In our Avocado Green Mattress, we use only the finest — 100% GOTS organic certified wool harvested from our farm in the Himalayas.

When used in bedding, our 100% GOTS-certified wool is great for many reasons, including:

(A) Thermal Comfort: Wool provides a high level of thermal comfort due to its outstanding insulating properties. Wool offers warmth under cool conditions because the natural crimp of the fiber allows air to be trapped. The thermal resistance of air means it is six to 10 times as insulating as any fiber. This insulating property of wool ensures that temperature changes are slow and gradual when used in bedding, avoiding rapid temperature changes.

(B) Moisture Absorption: Wool can absorb up to 30 percent of its weight in water without feeling wet. The reason for this is that its constituent keratin is very rich in amino acids, which easily bind together with water molecules. Wool is particularly hydrophilic when water is present in the form of vapor. As humidity levels rise, wool fibers absorb and store moisture, keeping the humidity at the skin surface relatively low. The absorbed moisture in the wool fiber can also be diffused into the atmosphere. This property ensures that you'll never experience that damp, clammy feeling with wool.
