Merino base layer tops: the finest fabric against your skin
Merino wool is a fantastic material to wear against your skin: it regulates temperature, doesn’t itch, doesn’t get smelly and is breathable. It may be more expensive than synthetic materials but is absolutely worth it. Here at addnature we stock a wide range of tops made from merino wool, from vest tops for ladies and men to long-sleeved models for cold weather to be worn under several other layers.

Warm Merino Baselayer Shirts

The warm shirts made of Merino wool are the best base layer to wear under an outdoor jacket, whether you're doing mountain sports or hiking. Merino baselayers are warm, thin, breathable, stretchy, easy to clean, and won't smell. So, merino wool is the best raw material for making Merino undershirts and Merino underwear, which are great for outdoor sports. Even when it's wet, the merino base layer gives off some heat. And the best part is that merino wool is made from raw materials that are all natural.

Where Do Merino Wool's Raw Materials Come From?

The Southern Alps are home to the Merino sheep, which is used to make Merino baselayer shirts. Extreme weather is something the animals have to deal with. The winters are cold and the summers are very hot. Sheep's wool is a type of natural, functional clothing that keeps you warm in the winter and cool in the summer. Merino wool is also naturally resistant to UV rays. These qualities are great for the Merino sheep to protect themselves from the weather at home, and they are also great for Merino wool underwear.

Why Merino baselayers?

Merino wool is a real "miracle fibre," and Merino base layers are very special because of it. A merino wool shirt is great for the outdoors because it has so many great qualities. Because of this, this high-quality wool is now used to make all kinds of base layers, from Merino base layers to Merino socks and back to Merino long-sleeved shirts.

Merino wool is different from "normal" wool in that it is very fine. Because of this, very thin tissue can be made. This is what makes Merino shirts so comfortable to wear. The Merino shirt sticks to the skin and doesn't feel uncomfortable or annoying, even after a long time of wearing it. Merino wool base layers are also great because they are very good at keeping the heat in. Even though a Merino base layer is very thin, it retains a lot of heat, making it the best base layer for the onion-shell principle.

Merino Wool's resistance to odor.

This shows another good thing: base layers made of Merino wool aren't likely to smell bad. So, if you are on a longer tour and can't change your Merino shirt every day, you won't be bothered by an unpleasant smell. A merino shirt is easy to clean and dries quickly, so it can be used again quickly. A Merino shirt is a good choice if you are looking for something to wear underneath your outdoor sports clothes.
