It is still to be answered. 

Many people are concerned over this question, whether merino wool shrinks with time or after washing. Considering the quality features of the wool, everyone is attracted to buy merino wool garments, but its shrinkage is their only concern. 

If you’re also here for this reason, here are some things that you need to know about merino wool. 

Why Use Merino Wool? 

Merino wool is one of the best wools in the market with multiple health benefits. Firstly, it’s all-natural and synthetic; it comes from merino sheep. Thus there’s nothing to worry about its chemical composition and harmful effects on the skin. 

Then, the wool is extremely soft and smooth to wear; you feel perfectly comfortable while wearing any merino wool garment. Also, the fiber being sweat-free and dry keeps you fresh and active all the time. Next, it is hypoallergenic and is best for people with allergies as it lowers the symptoms and provides relief. 

Several other features of this wool make it worth buying. All these features combine to cancel out people’s concern over its shrinkage. Thus, the decision to buy merino wool garments is never wrong unless they are brought from a reputed brand.

In addition, merino wool has the following worth admiring properties: 

Merino Wool Is Naturally Stretchy

Because the merino wool is made of a spring-like structure, it is thus naturally stretchy, and the fibers are impressively resilient. Due to this springiness, you can extend the garment up to 30% of its length without ever breaking the fiber. 

This natural springiness lets the wool fiber stretch back to its original shape. Compared with nylon, the merino wool is a stretcher, as the nylon fibers would start to break just after a 10% extension, which is 30% in the case of the merino wool. Also, Polyester fibers are stretched to a lesser extent. 

So, if you were thinking “how much shrink should I expect from merino wool,” then hopefully we have answered that. 

Thus, while wearing merino wool garments, you never have to worry about the deformation of their shape, as they always stay in their wear and tear shape. 

It is Naturally Durable

The merino wool is extracted from one of the toughest known breeds of sheep on earth; the merino sheep. It can thrive in the extreme environments in the rugged mountains only because of the natural composition of its fleece. 

The conditions and the harsh environments in the mountains require the sheep’s wool fibers to be strong and durable for maximum protection. If this does not happen, the sheep wouldn’t be able to survive. 

Thus, the wool extracted from the sheep is best for extreme weather and can surely impress you with its performance.
