Wool is a 'breathing' fibre that will never give you the feeling of being locked up. It has good isolating properties, and is very performing when it comes to regulating the body temperature. Wool can absorb up to one third of its own weight of moisture before it starts to feel wet. By absorbing moisture, wool reduces the amount of sweat on the body, thus also reducing the possibility of body odours.
People are not allergic to wool but it is true that wool, due to its structure, may itch. This depends on the fineness of the fibre.
Origin of the material
This wool comes from several countries: South Africa, South America, Australia, and European countries. It was spun, woven, dyed sandy brown ('desert') and finished in Europe. Note that the big wool producing countries all have a set of animal welfare laws which wool growers are bound to uphold.
Wool is a natural fibre and 100% biodegradable, can be cleaned less frequently and on lower temperatures thus saving energy and water. In addition wool garments often have longer lifespans, wool doesn't contribute to microplastic pollution of the air and surface water, and doesn't have to be ironed.
