The project stems from the idea of combining the thermoregulation and breathability of merino wool with the freshness and lightness of organic cotton, creating an innovative yarn for sportswear. The composition is 55% extra-fine merino wool and 45% organic cotton.
Thanks to the H2DRY treatment, the yarn retains the properties of merino wool — breathability, elasticity and moisture management — taking them to new levels of performance and ensuring comfort even in the most demanding conditions.
THERMOREGULATING
The unique crimped structure of the fibres creates micro air chambers that retain body heat, providing ideal insulation against both cold and heat. This feature helps maintain a balanced body temperature in all seasons. In addition, Merino wool can absorb up to 35% of its weight in moisture without feeling wet: water is trapped in the core of the fibre, while the surface remains dry, promoting sweat evaporation and the body’s natural cooling function.
BREATHABLE
The fibres have the ability to absorb water vapour produced by the body and release it gradually when the air becomes drier. In this way, Merino wool maintains a constant moisture balance, preventing sweat build-up and ensuring prolonged comfort. It also dries quickly, making it comfortable even on the hottest days or during intense physical activity.
ODOURLESS
Thanks to its unique structure, Merino wool fibre does not promote the proliferation of bacteria, which are the main cause of unpleasant odours. Keratin, a natural protein present in the fibre, helps to neutralise them, creating a natural self-cleaning effect. This means that Merino wool garments stay fresh longer and require less washing than other fabrics.

SOFT AND PRACTICAL
The fibres used are extremely fine, with a diameter of less than 25 microns: this makes them soft to the touch and non-irritating to the skin. Unlike other types of wool, Merino is comfortable to wear even in direct contact with the body. It is also easy to care for: it can be machine washed at low temperatures (30°/40°) without shrinking, retaining its shape and performance over time.
SUSTAINABLE
Obtained from natural, painless shearing, Merino wool is a completely renewable and biodegradable fibre. It requires no chemical additives for growth and uses only natural resources such as water, air and sunlight. Wearing Merino garments means choosing not only comfort and performance, but also a fabric that respects the environment and the communities that produce it.
H2DRY TREATMENT
Merino Bioma wool is further enhanced by the H2DRY treatment, developed to increase breathability and elasticity. Tests conducted at the Polytechnic University of Turin have shown that this technology promotes rapid moisture transfer to the outside, keeping garments dry even in extreme conditions. H2DRY preserves the characteristics of the fibre over time: garments retain their elasticity, fit and fresh appearance even after frequent washing, making them resistant to creasing and always comfortable to wear.

Lightness, freshness, natural softness and sustainability.
