Wool fibers are hydrophilic fibers – and that’s precisely what makes them extremely functional! They can absorb up to 35% of their own weight in moisture without feeling wet to the touch. The fiber surface remains dry, while the moisture moves to the fiber core. In contrast to down or polyester, wool thus feels warm and comfortable, even when wet. Of course, wool also dries out quickly, too – even keeping you refreshingly cool on hot summer days. And of course, the moisture is also released, providing refreshment in warmer temperatures: warm ambient air leads to a quick drying effect, which provides cooling evaporative coolness. Wool fibers are thus all-rounders that do exactly what you expect from them, whatever the season – they cool you down in summer, and warm you in winter.
Even our grandmothers knew that wool keeps us warm in winter – that’s why we all had those wonderfully itchy woolen jumpers. But keeping us cool in summer? Even our grandmothers wouldn’t have thought of that. The thermo-regulating qualities are based on two principles: On the one hand, wool fibers are highly rippled and provide plenty of space for air in the gaps between them. This air serves as an insulation layer, in both summer and winter, against heat and cold. The insulating layer also makes it possible for merino sheep to survive in the sometimes hot Tasmanian summers. The second principle is based on cooling by evaporative coolness. Wool can absorb more than 35% of its own weight in moisture (without feeling wet to the touch). If the ambient air is warm, the moisture dries faster, resulting in this refreshing evaporative coolness. If our grandmothers had known that, there would have been woolen T-shirts back then, too.
EASY TO CARE FOR
Even though wool has an inherent odor-neutralizing effect, you might find yourself in a situation where someone squirts ketchup on your product and you need to wash it. This is easier than you might think: Thanks to the addition of the corn-based fiber Ingeo, the material is very stable and easy to care for. You can simply machine wash it at 30° and then leave it to dry on a laundry rack. Just like for most functional clothing, you should nevertheless avoid dry cleaning and dryers.
TWO NEW COATS EACH YEAR
Wool is ecological by nature! Swiss sheep are shorn twice a year (in spring and fall) – so they grow a new coat all by themselves. The shearing process is purely manual labor and causes the animal absolutely no pain. And who wants to haul a thick fleece around with them on a hot summer’s day anyway?
Nobody wants to smell. With wool, you can get by with just a few items of clothing, even on mountain hikes lasting several days. This is made possible by the protein molecules in the merino fibers which simply destroy odor-forming bacteria. After the tour, you should simply leave your product to air, and you’ll be able to wear it again the next day. Your companions and the environment will thank you for it!
