How can it be? This blog post will explore the relationship between wool and sweating.

Let’s find out.

About Wool

Wool is a fiber made from the fleece of sheep. It is one of the oldest known manufactured fibers and was used worldwide for clothing, blankets, and other objects.

It is also used in industry to make products such as insulation, textiles, yarns, and cloth.

Surprisingly, the simple answer is no. While it is known for being extremely warm, it is also excellent at regulating your body temperature.

How does wool achieve this? The relationship between wool and sweating is simple:


Wool is breathable, so it will release that moisture back into the air. That means that while it might absorb your sweat, it won’t make you feel wet or uncomfortable. 


Wool is also absorbent, so it can absorb up to 30% of its own weight in moisture.

Helps regulate body temperature

Wool helps regulate body temperature by wicking away moisture from the skin.

When it’s hot outside and you start to sweat, the perspiration is drawn away from your body and evaporates more quickly, keeping you more relaxed.

In cooler weather, it helps insulate your body by trapping heat close to the skin.

So whether you’re trying to stay warm or cool, the thread can help you regulate your body temperature.

Types of Wool and Sweating

Of course, not all fabric is created equal. Some threads are better at wicking away moisture than others, and some are better at insulating against heat loss.

Factors to Consider

So if you’re considering investing in some wool clothes, here are a few things to keep in mind:

  • The type of wool: Generally speaking, merino wool will be more breathable than other types of wool-like lambswool or cashmere. This means that you’ll likely sweat more in merino clothing than in different types.
  • The construction: Well-made wool garments are usually well-wadded, which helps to keep the fabric tight against your skin and minimize airflow. This can help to reduce sweating.
  • The climate: Some climates are warmer than others, which will also affect how much you sweat. For example, if it’s hot out and you’re wearing a wool garment, you’ll sweat more than if it’s cold out and you’re wearing a synthetic garment.

What about Merino Wool?

Merino wool is a type of fine wool that comes from the Merino sheep. The fleece of the Merino sheep is prized for its softness, warmth, and breathability.

Merino wool is often used to make sweaters, hats, scarves, and other winter wear. It is also used in insulation and in upholstery padding. Because it is so soft and lightweight, it is also often used in baby clothes and bedding.

How to Stay Cool in a Warm Weather Clothing Style with Wool Blend Fabric

  • A merino wool blend would be a great choice for this. It will help to wick away moisture and keep you cool, while the synthetic fibers will provide structure and support to the garment.
  • Another great option for a summer wool blend is linen. Linen is very breathable and will help keep you cool, while it will provide some warmth and structure to the garment.

With the right fabric, you can stay cool and comfortable all summer long.
