The Core Wool Merino Set includes a long-sleeved baselayer jersey and underpants made of a soft merino wool and polyester blend that keeps you dry and warm all day long. The combination of mulesing-free merino wool and highly functional polyester ensures excellent thermoregulation during low to medium-intensity activities. In addition, the fabric’s soft and fine fibres provide a smooth touch against the skin, making the garments a great choice for alpine skiing, trekking and hunting.
