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 keep you dry and either cool or warm depending on the intensity of your activity. Whether you prefer a more relaxed pace or are active until sunset, the lightest merino shirt in our collection is always with you. Enjoy natural comfort for your next outdoor adventures.
