The long-sleeved Merino 160 base layer shirt, our lightest base layer made from pure merino wool, is produced in our factory in Europe from 160 g/m² lightweight mulesing-free wool and is the ultimate choice for almost any outdoor activity on milder days. This is thanks to the moisture-wicking and thermoregulating properties of wool, which keeps you dry and cools or warms you depending on the intensity. Whether you're taking it easy or staying active until sunset, the lightest merino shirt in our collection is always with you, everywhere. Enjoy natural comfort for your next outdoor adventures.
