What Kind of Wool is Merino?

Merino sheep are the only kind that produces the type of wool known as merino wool. This breed of sheep is indigenous to New Zealand and Australia, and its wool is highly regarded due to its exceptional softness and fineness. Merino wool is significantly lighter and has a more delicate texture than traditional wool.

Because of this, it is an excellent choice for the fabric of performance clothing because it will neither slow you down nor make you feel too hot. Merino wool is naturally resistant to odors and wicks away moisture, making it an excellent choice for sports that generate a lot of perspiration, such as jogging.

What Characteristics Should You Seek in a Merino Wool Running Outfit?

When looking for running gear made of merino wool, you should consider a few factors while buying. First and foremost, you will want to verify that the equipment is constructed entirely of merino wool.

Several manufacturers combine merino wool with other types of fibers, most frequently polyester, to reduce costs. However, because of this potential to lessen the positive effects of merino wool, it is better to stay with clothing and equipment manufactured exclusively from this natural fiber.

Consider the fabric’s weight as another important consideration before making your purchase. Merino wool may range from highly lightweight to weight between the extremes. Your choice of weight should be based on the weather conditions where you reside as well as the kind of jogging you undertake.

For instance, if you live in a warm environment and do most of your jogging during the day, you should probably be OK with a lightweight merino wool fabric. This is because merino wool breathes better than other types of yarn and is more breathable. 

On the other hand, if you live in a cold region and do much jogging at night, you should probably go with a fabric that has a weight somewhere in the middle.

Last but not least, you need to check that the merino wool clothing you buy is the right size for you. Because this natural fabric tends to stretch, selecting clothing that fits comfortably close to the body without constricting is essential.

If you are undecided about the size to select, it is usually recommended to err on the side slightly larger than your typical size. This will ensure that you have enough room to move around comfortably. If you do it this manner, you won’t have to worry about whether or not the gear will still fit once it has been stretched out.

Why is Merino Wool the Best Fiber to Use for Making High-Performance Fabrics?

Odor Control:

Merino wool has a combination of physical and chemical properties that, when combined, make it the most naturally odor-resistant fabric that can be found elsewhere in the world. 

To begin with, fiber does not have much attraction to microbes. In most cases, germs will be drawn to the smooth, positively charged sides of synthetic fibers; however, they will not be drawn to the scaly, neutrally charged face of merino fibers. 

Next, merino has a considerably better ability than other yarns to absorb moisture. When this moisture is locked up inside the structure of the fiber, germs can’t reach the fiber’s surface.

Because this moisture is transferred away from the skin effectively, your perspiration does not sit on the surface of your body for as long as is necessary for bacteria to proliferate and produce smells. Merino wool clothing is an excellent option for those who despise the scent of synthetic fibers.

As a part of our testing, we kept our shirts on for the whole day after a hard run in the morning without taking a shower, and we also wore them for five to seven consecutive days of running without washing them in between. 

An experiment that might go either way, but the merino wool didn’t smell bad at all. Period. That by itself ought to be sufficient justification for giving it a go.


Because the center of a merino wool fiber is inherently hydrophilic, it draws away moisture from the skin’s surface and towards the drier environment outside, where it may evaporate. 

The way it works is like an extension of the natural cooling mechanism that your body already has. Compared to synthetic fabrics, Merino shirts take significantly longer to dry thoroughly during and after usage. This is because the ends of the fibers have a propensity to collect moisture. 

However, because the fibers produce a balance in the moisture conditions, the fabric is pleasant to wear in a more extensive variety of climatic situations.

Insulation and Absorption Capacity

Merino wool can absorb up to one-third of its weight in moisture without becoming wet or sticky. Because of this, it can keep the surface of your skin dry while the environment is warm, but more significantly, it maintains a layer of dry air near the skin when the environment is wet or cold, which helps your body retain heat. 

In addition, the breaking of the water’s hydrogen bond that occurs when wool absorbs moisture produces heat through a chemical reaction between the molecules of the thread and the water. 

Because of all these characteristics, wool is an excellent temperature regulator in damp settings; it may be drenched and keep your body warm. This equates to outstanding protection against hypothermia for ultrarunners, whether participating in a rainy 50-miler or the frigid night portion of a mountain 100-miler.


A reassuring yes. If you are surprised to learn this, you most likely have images of your father’s army blanket or your grandmother’s uncomfortable old sweaters running through your head. Merino wool is not the same as your father’s wool. 

The production process has improved significantly over the past few years, which is shown in the fact that modern fabrics are every bit as velvety smooth as any other you can find. 

Merino wool provides comfort beyond the surface because it helps maintain a healthy body temperature even as it wicks away moisture.


The fact that merino wool does not retain odor even after being worn for seven days in a row throughout a series of running tests is only one of the ways that these tests demonstrated the fabric’s durability. Wool fiber, when seen on a microscopic scale, assumes the form of a coil spring; this gives wool its inherent elasticity. 

When wet, the fiber can be stretched by up to fifty percent, whereas when dry, it can only be extended by thirty percent. Additionally, the thread can be bent or bent back on itself hundreds of times without becoming thinner or breaking.

We’ve had a couple of shirts made of merino wool for the past few years that have shown no indications of wear and tear despite being worn multiple times each week. Keep this information in mind while looking at the pricing of merino clothes; as a rule, they are not inexpensive. 

Merino garments are often expensive. On the other hand, each piece of clothing represents an investment that will most likely be profitable over a lifespan far longer than synthetic clothes.


The shearing of sheep and the manufacture of wool is one of the garment industry’s procedures that has the most negligible negative impact on the natural environment. It comes from an entirely natural and sustainable source. 

Because it does not need to be washed after each use, the amount of water and energy used for laundry in your home can be reduced. In addition, once you have finished using the product – regardless of how many years this may take – the material may be recycled in its entirety or broken down naturally. 

Farmers of sheep and businesses that manufacture clothing made of wool are consistently lauded as being among the most socially and morally responsible of all available types of enterprises by advocacy organizations and environmental watchdogs.
