Performance and warmth – but naturally. The Natural Merino 260 Base Layer with half-zip is made from extra-warm and exceptionally soft mulesing-free merino wool with a weight of 260 g/m². The material is not only naturally thermoregulating but also antimicrobial (i.e., odor-reducing). This super comfortable base layer for cold days is the ideal choice for those who prefer natural fibers. It is manufactured with the utmost precision in our factory in Europe and performs just as well while skiing and tobogganing as it does on cozy days at home. Natural comfort for your next outdoor adventures.
