Technical information

How does wool reduce the proliferation of odours?

Thanks to its excellent capacity to absorb moisture, wool reduces bad odours. Indeed, merino wool does not only absorb the water contained in sweat, it also absorbs the emanation of bad odours.
It can therefore be worn for several days in a row, which means that you don't have to take as much clothing on a trek!

How did we improve the durability of our T-shirt?

Use of a BETA-SPUN yarn structure in which the polyamide threads coat the Merino wool fibres and protect them from rubbing and cuts without affecting their technical properties.

Reducing the cooling/freezing effect

Merino wool is capable of absorbing a large part of the body's moisture after exercise and heavy sweating. This prevents evaporation and thus maintains body temperature. (Unlike with synthetic material).


For this product, we only use wool from Merino sheep raised on farms in South Africa that do not practice mulesing. We decided to build a partnership with a group of breeders (Konsortium Merino) to guarantee respect for animal welfare and the environment. This means we have full traceability, which allows us to guarantee the origin of the wool.
