What does ethically sourced mean?

We’ve made a commitment to use ethically sourced wool which means the farmers we partner with do not engage in animal cruelty. Each Meriwool item is made from merino wool, a specific material that’s produced by sheep with wrinkly skin. This can sometimes become problematic in the summer and leads some farmers to practice mulesing — a way to continue wool production that’s detrimental to the animal’s health. Let’s learn more about this sustainable, biodegradable, and 100% mulesing-free material.

history of merino wool

Where does merino wool come from?

Hailed as a “miracle fabric” in the 12th century in Spain, merino wool played a huge role in keeping people warm. As most only had a few garments to wear, this material was loved for its strength and comfort. It was so revered that exporting merino wool outside of Spain was punishable by death! In 1788, several dozen merino sheep were transported to Australia after the Napoleanic Wars and soon grew to over 2 million by 1830. Around this time, merino wool was used to craft clothing regularly.


Unlike other types of wool that can be bulky or itchy, merino wool is one of the softest and warmest materials around. It features natural odor-resistant and fire-resistant properties and is adaptive, meaning it helps to regulate your body temperature so you’re never too hot or cold. Merino wool wicks away moisture and absorbs sweat with ease, allowing your outdoor adventures to be incredibly comfortable. It’s also a renewable and biodegradable material and creates very little pollution. Learn more HERE

How do the sheep get treated?

Meriwool sources wool exclusively from Australia and New Zealand, two countries that pride themselves on the humane treatment of sheep. Both countries enforce strict standards for raising sheep as well as how the wool is harvested and are committed to no mulesing, a practice that’s painful and dangerous for sheep.It’s our promise to our customers that we only use ethically sourced wool from sheep who are treated with care and do not support farmers who engage in mulesing.

Mulesing free
What is Mulesing?

A dangerous and painful practice, mulesing is done to prevent flystrike, an infestation of flies on the sheep’s skin. The procedure involves restraining the sheep and cutting away portions of their skin, often without the use of painkillers.

Does MERIWOOL Practice Mulesing?
Meriwool’s yarn is never obtained from farmers who practice mulesing. Our standards and certifications ensure that our merino wool is 100% cruelty-free, giving you peace of mind whenever you purchase one of our garments.
