What is Merino wool made of? Proteins composed of amino acids and natural compounds. Merino wool is a natural, renewable fiber—meaning one sheep can grow four to five pounds of wool per year. Plus, this fiber has evolved over the years to keep sheep comfortable in harsh environments. These happy animals hang out in temperatures that range from 5 degrees to 95 degrees—no problem. It’s a pretty amazing fiber.
It Helps Regulate Body Temperature
What is Merino wool really good at? Helping keep your body at a stable temperature. When it’s cold outside, the natural crimps and bends in its fibers trap air, insulating you. When it’s warm outside, it transports sweat quickly away from the skin, helping to keep you cool and dry.
It Helps Keep You Dry and Sweat-Free
This benefit of wool gets a bit technical—so bear with us. Merino wool transports sweat and moisture away from skin as a vapor. Merino fibers are inherently porous. They’re composed of little plates that moisture vapor can get in between—meaning they can soak up your sweat before it pools into a liquid on your skin. Synthetic fabrics are not porous. They usually wick sweat when it’s already a liquid, and then your body has to heat it up to evaporate it—making you feel clammy in colder weather. Merino takes a step out of the process, which helps you stay warm and dry when you’re moving and playing outdoors.
