About Merino Wool FAQs

What Is Merino Wool?

Merino Wool is the world’s most versatile performance fabric. It comes from high-elevation areas in New Zealand and Australia where Merino sheep run wild. The Merino breed’s wool is revered for its durability and moisture-wicking capabilities. Under a microscope, its fibers measure half as thick as human hairs but are twice as resilient, capable of being twisted up to 20,000 times without breaking.

Is Merino Wool itchy or soft?

Merino Wool is incredibly soft and never itchy. Merino fibers are 1/3 the diameter of a human hair, making them more flexible and supple. So, when pressed against your skin, they’ll bend to provide a delightfully soft touch rather than being itchy and irritating.

What is Merino Wool made of?

Merino Wool fibers come from the fleece of Merino sheep, a breed of sheep known for their very fine, soft wool. It’s the world’s finest wool and revered for its inherent qualities, including durability. After being sheared and cleaned, the fibers are then spun into yarn and prepared for knitting.

Is Merino Wool good for summer?

Merino Wool is perfect for summer, helping keep your feet dry and sweat-free on even the hottest days. It’s one of the most comfortable materials to wear in the summer because it’s breathable and moisture wicking. Plus, it’s also thermoregulating so your body doesn’t overheat.

Is Merino Wool good for winter?

Merino Wool is great for winter because it helps keep your feet dry and regulates body temperature. Its fibers are made up of little crimps and bends that trap air and provide insulation for your feet, making it ideal for cold days and even colder nights.

Are Merino Wool socks worth it?

It’s worth investing in a pair of high quality Merino Wool socks if you value fresh feet. Darn Tough socks hold their value and are Guaranteed for Life. So, if you buy one pair and they rip, tear, or puncture, we’ll replace them with a brand-new pair at no additional cost.

Is Merino Wool good for hiking?

Merino Wool’s natural qualities – moisture-wicking, thermoregulating, and odor-resistant – make it the best fabric for hiking. It helps prevent blisters in hiking boots and dries quickly after getting wet. It’s also exceptionally breathable and durable for hiking through rugged terrain

How long does Merino Wool last?

We combine Merino Wool with Nylon and Lycra Spandex to create a resilient performance fabric that lasts forever. Backed by our Unconditional Lifetime Guarantee, Darn Tough Merino Wool socks offer long-lasting durability that you can trust for prolonged hours on your feet.

Is Merino Wool moisture wicking?

Merino Wool is moisture wicking and naturally pulls perspiration away from your skin when your feet start sweating. It maintains its ability to insulate and keep your feet warm even after it gets wet, making it ideal for managing sweat and regulating body temperature.

Can Merino Wool get wet?

The benefit of wearing Merino Wool is that it helps keep your feet dry and warm even after it gets wet. The fibers can absorb up to 30% of their weight in moisture without losing their ability to insulate. And after absorbing that much of its weight in water, it still doesn’t even feel like it’s wet.

Is all Merino Wool the same?

No, there are different types of Merino. Depending on the diameter of its fibers, some Merino is softer than others. At Darn Tough, we utilize the finest, highest-quality Merino fibers with varying weights and diameters for a next-to-skin feel that’s exceptionally comfortable.
