The Women's Puremerino Half Zip is a next-to-skin base layer crafted from 100% pure 18.4 µm merino wool, knitted at 200 g/m² for a lightweight, smooth feel across all seasons. The slim fit and high collar with half-zip venting make it a practical thermal layer for activities ranging from trail running and cycling to ski touring and snowshoeing. Because the wool is unblended and untreated, it retains its full natural thermoregulating, antibacterial, and moisture-managing properties, and the fabric is fully biodegradable and recyclable at end of life.
