Is functional wool clothing scratchy?
Wool clothing is a staple in many athletes' wardrobes, especially during the colder months. It offers excellent heat and microclimate regulation, breathability, and low odor absorption. However, a common misconception many associate with wool clothing is that it's scratchy and uncomfortable on the skin. But is that really true?
1. What causes the scratching?

The itchiness of wool clothing is generally related to the thickness and structure of the wool fibers. Coarse wool has thicker, less crimped fibers. Therefore, more of the wool fiber's cuticle rests against the skin, which can be perceived as unpleasant. The finer the wool, the less skin contact: Therefore, even with sensitive skin, products made of merino wool and cashmere, for example, are rarely perceived as itchy.
2. Tips against scratching
- Choosing the right wool type: If you're sensitive to itchy wool, opt for fine wools like merino or cashmere. Our Grüezi bag® WoodWool shirts are made from a velvety-soft material: 50% merino wool and 50% wood fiber. Therefore, they're hardly itchy and offer all the benefits of wool clothing.
- Proper wool care: A common mistake people make is washing wool clothing incorrectly. If wool isn't washed properly, it can lose its softness and become more itchy. Use special wool detergents and pay attention to the correct washing temperature. Wool clothing is best washed by hand or on the gentle cycle of the washing machine at a low temperature.
3. Fazit
Wool clothing doesn't necessarily have to be scratchy. Choosing the right type of wool is crucial to maximize comfort. If you have sensitive skin, opt for softer wools like merino wool or cashmere.
Wool offers numerous advantages over synthetic fibers or cotton in terms of warmth, moisture management, and sustainability, making it an ideal choice for many.
And wool is a renewable and biodegradable raw material, naturally odor-resistant, and easy to care for. With proper care, wool clothing can be worn for many years.
