These thin, lightweight socks from William Ellery blend 60% merino wool with 25% brushtail possum fiber and 15% nylon to deliver warmth well beyond standard merino options. Brushtail possum fiber features a smooth, hollow hair structure that traps heat efficiently — making it 55% warmer than merino wool alone while remaining 14% lighter. The natural properties of the fiber also contribute to quick-drying performance and antimicrobial odor resistance, keeping feet comfortable across extended wear. Crafted in New Zealand.
