The Puremerino Half Zip is a next-to-skin base layer crafted from 100% superfine 18.4 micron merino wool at 200 g/m², offering natural thermoregulation, odor resistance, and soft-against-skin comfort without synthetic blends. A slim fit with a high collar and half-zip allows precise ventilation control, while the slight back drop adds comfort during active movement. Suitable across all four seasons, it works equally well as a running or hiking layer in warmer months and a ski touring or ice climbing base in winter. The pure, unblended wool construction makes the fabric fully biodegradable and recyclable at end of life.
