Why you should wear merino wool in the summer

Perhaps, the best argument is that about 1 billion sheep can't be wrong! In the summer the sheep shed and change into lighter version of their coat and obliviously thrive excellent, even in hot areas.

We have learned from the sheep; our lightweight textile has a weight of 135g/m². It makes the T-shirt feel light, airy and extremely suitable for the summer weather and indoor use as well.

Merino feels dry to the skin

Merino fibres can absorb moisture equivalent to 35% of its weight without feeling wet to the skin and it evaporates quickly into the air. Therefore Merino T-shirts feels comfortable against the skin and does not stick to the body.

Cooling your body

Evaporation from the fibres works chilling, the same principle as a freezer or a fridge. When the liquid evaporates, energy is used in the form of heat which provides a temperature reduction. This effect is greater in wool in comparison to other fabrics, especially for merino wool.

You're not going to smell

In contrast to the cooling effect, this is shown in reality and not only in a study. The best example is my friend Jens, who tells how they use wool in the Sirius dogsled patrol. 

The reason it works is that wool contains lanolin that breaks down the bacteria that create odour. It allows you to wear the same Merino T-shirt for several days without developing odour. 


There is scientific evidence

10 trained men wore T-shirts in three different fabrics in temperatures of 8°C and 32°C. In both cases, they replied that the woolen T-shirts were the most comfortable. But the result was also measurable:

Wearing polyester: Sweating after 9 minutes
Wearing merino wool: Sweating after 15 minutes

The subjects began to sweat after 9 minutes, when they wore polyester, 15 minutes went before they began to sweat in T-shirts made of merino wool (even though that most fabrics are marketed as suitable for training, are made of polyester).
