Pure merino wool provides excellent warmth when staying outdoors on cold days or during short sports sessions outdoors. Do winter sports for several hours, prefer a merino-synthetic mixture that wicks sweat away and dries faster.

The Merino sheep species has a lot of skin due to overbreeding, in the folds of which fly maggots can nest. To prevent this infestation, many farmers in Australia and New Zealand use it Mulesing method back. Doing so cut out excess skin from the sheep’s tail, which is very painful for the merino sheep.

While some manufacturers sell their products as mulesing-free, point that too GOTS seal and the designation Kbt a animal welfare. With Merino wool products from South America, you can also be sure that this painful procedure has not been used because the type of fly does not exist there.

So you can put together the respective upper and lower part, also in different sizes. Because very few people need exactly the same size of clothes on top and bottom.
The length of the shirt and trousers is also variable. In the deepest winter, grab a long-sleeved shirt and long trousers, at a slightly higher temperature, exchange the former for a t-shirt and at a fitness session in the warm, choose a short merino-underwear combination.

- ideal source of heat in winter

- less suitable for summer

Due to its excellent body temperature regulation, the Merino material is also suitable for ski underwear.
