What Makes Merino Wool So Special?
Merino wool comes from Merino sheep, most of which are raised in Australia and New Zealand. Merino wool is not the same as traditional wool. Merino wool is finer and softer than traditional wool, meaning it is more comfortable when worn against the skin.
Merino wool is breathable which means it keeps you warm in the winter and cool in the summer. Merino wool also does not stink, it absorbs moisture, and is more comfortable than most synthetic fibers. On top of it, Merino wool is biodegradable and renewable which makes it a worthy choice for eco-friendly fashion lovers.
