- Merino wool
Merino wool is one of the most appreciated fabrics for its quality and characteristics. Merino wool is obtained mainly from Merino sheep originating in New Zealand. This breed of sheep is found in many corners of the world, however the wool is recovered from the natural sheep of that country. The difference between these Merino sheep and those of the rest of the world is the skin, which is thicker to protect them from extreme weather conditions. Due to the fineness of the fiber, Merino wool is much more pleasant on the skin. Sometimes the wide fiber diameter of ordinary wool irritates dead skin cells, while Merino wool creates the opposite effect. Which is why Merino wool irritates much less. Wearing sports equipment made from Merino wool guarantees outdoor sports enthusiasts a soft and comfortable touch to the skin, as well as warmth and lightness, a very important feature for someone who is constantly on the move.REF: 4521553-010
