5 reasons to wear merino wool | kari traa

Trend Guide


Norwegians, like Kari, love to wear wool – for everyday use as well as when exercising. For years, we have been dressing according to the three-layer principle, with wool on the inside. This is not by chance.

Despite the fact that we are constantly researching new technical fabrics, the natural benefits of wool have proved to be unbeatable – in addition to being the most environmentally friendly material we have. So, to all of the potential skeptics out there, and to those who just want to know more about wool, here are five reasons to wear wool, also in the summer.

Environmentally Friendly - Free from Micro-plastics

Much of our training clothing consists of polyester, which is actually plastic. You have probably noticed that it doesn’t take long before these garments start smelling after exercising, which in turn means that we have to wash them frequently. In the washing machine, polyester garments release microplastics, which end up in the sea and damage life down there. Wool, on the other hand, is 100% renewable and natural, and is therefore one of our most sustainable materials. It does not necessarily have to be washed, which leads us to the next point.

Wool is Self-Cleaning and Prevents Odors

Merino wool has a natural resistance to the growth of microorganisms and odors, and can be used for several days without smelling. The reason for this is a combination of the merino wool absorbing moisture and the wool fibers having a negatively charged, scaly surface. Bacteria, which leads to bad odor, thrives best on a smooth, positively charged surface such as synthetic fibers. All you need to do after use is to air your woolen garments well. Then you also avoid unnecessary washing and wear.

Helps Keeping Even Body Temperature

We all know how uncomfortable it is to be too hot or too cold when active. Wool has unique insulation properties that both absorb and release moisture, allowing your body temperature to adjust to a comfortable level.

When it is cold outside and we sweat, the wool will absorb the moisture and initiate a process where it generates heat. The heat is stored in air pockets in the wool fibers, and thus does not freeze - even when it is cold. Wool can hold up to 35% of its own weight in moisture before it feels wet. This makes you feel drier in wool and is why even moist woolen clothing provides warmth.

When you get too hot, wool ensures that temperatures stay cool through evaporation, just like our bodies when we sweat to cool down.

Therefore, wool is just as comfortable when used in spring and summer. Change to a thinner wool model with mesh when winter is over.

Silky-smooth against the skin

Merino wool has longer and thinner fibers than other types of wool, and garments made from merino wool, feel silky smooth and light on the skin. The fibers are also more elastic than ordinary wool fibers, curl less, and provide a better fit. If a garment has shrunk after washing, it can often be stretched back to its original shape.

Healthy For The Skin

The ability of the Merino wool to control temperature and humidity, as well as its antibacterial properties, helps create a healthy microclimate for your skin - which in turn can provide relief from eczema and other skin problems. A study published by the "Journal of British Dermatology" showed how children with eczema had fewer symptoms by using super fine merino wool over an extended period of time. Many people may have experienced how rough and thick wool causes itching and irritation. For wool to be soft and soothing it must be less than 22 microns. The merino wool used in Kari Traa products is always below 21.
