Authentic Icelandic Wool

– A Key to Survive the Tough Icelandic Weather

Evolving over 1,100 years of exposure to the sub-Arctic climate, Icelandic wool has a distinctive combination of inner and outer fibers. The outer fibers are long, glossy, tough and water-resistant, while the inner ones are fine, soft, and insulating, providing great breathability and high resistance to cold.

Authentic Icelandic Wool is free of any residues of pesticides and herbicides as their usage in sheep farming is unknown in Iceland.

Icelandic high-quality wool gives many desired benefits outside warm breathable clothing and durable carpets. Wool acts as an air purifier for both dust and harmful volatile organic compounds. It is flame resistant and does wonders in absorbing unwanted noise.
