■ What is Merino Wool?

Merino wool is a high-quality natural fiber made from the wool of Merino sheep.

Merino sheep are mainly raised in Australia, New Zealand, South Africa, and Argentina. Their wool is finer than regular wool, with a diameter of only about 18 micrometers, which is less than 1/3 the diameter of a human hair. Therefore, it is characterized by being softer and having a better feel against the skin compared to regular wool.

■ Characteristics of Merino Wool

The greatest features of merino wool are its high thermal insulation and breathability. Because the fine hairs can contain a lot of air, warm air can be trapped inside the body, blocking cold air from outside. Additionally, due to its high breathability, sweat is absorbed and evaporated quickly, making it dry quickly and less stuffy, allowing for comfortable wear. Furthermore, merino wool has excellent antibacterial properties, which can suppress the growth of bacteria that cause unpleasant odors (odor control).
Thus, by adjusting its thickness and density, it is a highly versatile item not only for autumn and winter but also for spring and summer seasons.

On the other hand, because merino wool has fine fibers, while it is soft and light, it is prone to pilling and friction can damage the fibers. Also, depending on the product, the price can be high.

Therefore, merino wool is primarily used in high-performance outdoor wear and fashion items. Recently, it has also been used in everyday wear such as underwear, tights, socks, and masks, taking advantage of its fiber characteristics, and is gaining attention for its health and comfort benefits.

As such, merino wool is a high-quality and high-performance natural fiber, and due to its excellent thermal insulation, breathability, and odor control, it is used in various clothing items.
