Merino wool is a natural fiber grown by Merino sheeps. It’s thinner than regular wool making it softer and more comfortable on your skin. When you wear it next to skin, a lot of benefits come with it. Merino wool is breathable and temperature regulating thanks to the air chambers that are within the fabric that keeps the heat close to your body. Also, Merino wool doesn’t hold on to unpleasant doors thanks to its scaly surface that makes it impossible for bacteria to set in and it can hold up to 33% of its own weight in moisture, leaving the surface comfortably dry even during rainy days.
