Let's Talk Merino Wool

Let's Talk Merino Wool

Take a look at the history and uses of this very special wool and explore just whats makes it different.


Rather underrated, wool plays a very major part in human history. It has been used as clothing for many millennia, where primitive humans would clothe themselves in the skins of wild sheep before there domestication. It has been keeping us warm since. During Roman times, there were the first signs of selective breeding to make a superior fleece, through to the ascendancy of wool during the Middle Ages in Europe where wool, the central block in the medieval economy, had a major surge in quality. It was during the 12th century when the foundation flocks of merino sheep arrived in Spain. A monopoly was built around them and the Spanish became so protective of this wool, finer and softer than any before it, that it became a crime punishable by death to export the sheep from Spain. This law continued until the 18th century, where in 1788, the first merino sheep arrived in Australia, 70 at first, there are now today over 56.6 million merino sheep down under. The largest amount in the world and double the human population. Merino has been since perfected for strength and softness of fibre. The best Merino is said to come from Australia and New Zealand.

Where does Merino differ from other wool?

All wool in general is a fantastic material, we haven’t ever truly managed to replicate all of its features in anything synthetic. It’s a water-resistant fibre which still maintains a lot of warmth even when soaked through. It’s flame retardant, you can sit by the fire and not worry about stray sparks, synthetic fibres melt. It’s flexibility and durability allow it to withstand great amounts of pressure and use much longer, it’s a very long-lasting material that can be used for years with no issue. Lastly, wool is antimicrobial and does not hold onto body odour nearly as much as synthetic materials do. All of these features are common of all wools, so where does merino differ?
For starters, standard wools are very itchy. To those with sensitive skin, wool can be irritating. Merino is a much finer fibre, incredibly soft and much less itchy making it ideal for next to skin garments like base layers, socks and underwear. Thanks to these thinner fibres, it is quite lightweight and packs tremendous warmth for how little it does weigh. It also however in lighter constructions, performs brilliantly in hot weather as well, keeping you cool and dry due to its excellent ability to efficiently wick away moisture. Again, its finer fibres make it more air permeable than a standard wool, it breathes much better and dries much faster than other wools. Merino wool garments are used as base layers by top mountaineers and skiers. Fun fact: Due to the antimicrobial properties, astronauts use them under space suits to keep their body odour out for as long as possible for long hauls in outer space.
