The Glacier Brushtail Sock blends 60% merino wool with 25% brushtail possum fiber — a natural material with a hollow hair structure that traps heat more efficiently than merino alone, making it 55% warmer by weight. At 15% nylon for durability, the sock sits in a thin, lightweight profile suited to active use across hiking, travel, and cold-weather pursuits. Brushtail possum fiber is inherently antimicrobial and quick-drying, reducing odor buildup on multi-day use. Crafted in New Zealand by William Ellery.
