Quick Merino Facts
View allWhat is Merino wool and where is it grown?
Merino wool is a protein fiber naturally grown on the breed of sheep call the 'Merino'. It is the finest and softest wool grown of all sheep across the world.
The Merino breed originated in Spain, but since the late 1800's has been primarily grown in Australia where it has been perfected to grow a softer and longer fleece than ever before.
In fact, wool is the world's oldest textile trade, having proven it's worth for over 5000 years and counting.
What elevates Merino wool above other fibers?
Merino wool naturally holds an abundance of unique characteristics not seen in any other fibers, natural or man-made. This is what makes Merino a sought after fiber for all types of clothing:
- Temperature Regulation: Keeps you warm in cold weather and cool in warm conditions.
- Breathability: Allows air to circulate, preventing overheating.
- Moisture-Wicking: Draws sweat away from your body, keeping you dry.
- Odor Resistance: Naturally resists odors, even with repeated wear.
- Softness: Fine fibers make it incredibly soft and comfortable against the skin.
- Lightweight: Offers warmth without the bulk, perfect for layering or travel.
- Hypoallergenic: Gentle on sensitive skin, reducing irritation.
- Sustainability: Biodegradable and renewable, making it eco-friendly.
- UV Protection: Provides natural sun protection, blocking harmful rays.
- Durability: Strong and resilient fibers ensure long-lasting wear.
These qualities make Merino wool an ideal fabric for both luxury and activewear
How does Merino compare to cotton?
Merino and cotton exist to serve two different purposes.
Merino wool is grown to protect the sheep from wind, rain and varying temperatures all year round. This is why Merino wool is fast drying, anti-bacterial (odor resistance) , UV resistant and temperature regulating. Merino wool is designed to keep the wearer comfortable and protected during all weather types. It will still keep you warm even when wet.
Cotton, on the other hand, exists to trap and hold moisture for the plant it is grown on. Cotton therefore has great absorption but is slow to dry, and stays wet for longer. This is why towels are made from cotton.
It is not anti-bacterial, which is why it often smells after wearing, and has very poor temperature regulation as this is not what it exists in nature to do.
