Friendship with nature ... At the heart of the production of the New Zealand's company Icebreaker lies the breeding of the so-called merino sheep - unlike regular sheep, merino sheep are created to survive the hot summers and the freezing winters in New Zealand. Their incredible fleece keeps the cool at high temperatures, and provides the necessary warmth on cold days. Icebreaker combines these natural wool with synthetic fibers, enhances the functionality of the merino and provides stretching and comfort in heavy traffic. The result is extremely mild and soft, warm in cold weather and cool in the heat of matter, with a miraculous ability to withstand odors. It is naturally renewable, recyclable and biodegradable!
