Merino sheep wool is a wool of exceptionally good quality.

Products made from "curly" merino wool are fluffy, soft, so this feature increases the ability to insulate heat. Heat is felt in cold and hot weather. Wool absorbs moisture very well: if the air humidity is 100%, then wool absorbs as much as 40% of moisture without feeling wet. When wool absorbs moisture, a number of chemical reactions occur in it, which release heat into the environment and the fabric itself remains warm, which allows the body to adapt to temperature fluctuations. Moisture evaporates from wool quite slowly: the upper layer of wool (cuticle) consists of tiny micropores that allow the fabric to breathe - the pores are so tiny that water, in the form of droplets, cannot penetrate the surface of the fabric, so moisture is removed only through the upper pores, while preventing water from penetrating inside. The human body regulates body temperature by increasing superficial blood circulation and, if necessary, sweating, so wool's unique ability to allow air and water vapor to pass through leaves a feeling of comfort.

The curling of the wool hair gives it elasticity and flexibility. The elasticity ensures that the thermal insulation does not disappear even when the garment is worn for a long time. Such products do not wrinkle and quickly return to their original position. Wool is easy to care for: thanks to the chemical reactions that occur, wool is easily cleaned. After airing woolen clothes, sweat or other odors disappear.
Merino wool is suitable even for people with allergies: wool consists of the same protein substances as human skin - proteins and keratins.
