We've forged an exclusive partnership with leading European fabric mill Thygesen & Birk to develop our lightweight Aeron Merino Mesh Base Layer, which delivers exceptional breathability, moisture management and insulation all year round.
Based in Denmark, Thygesen & Birk have dedicated more than 15 years to the development of Sportwool®, which blends high-quality synthetic fibres with the natural power of extrafine Merino wool for elite performance apparel.
