Fibre & care
80% yak cashmere, 14% Nylon, 6% Elastic
The Purists are knit from 100% Mongolian yak cashmere yarn: yak down is hand-combed from the animal once a year by Mongolian herders, then spun dye-free at 14–17 microns, finer than most cashmere.
Care: wash cold on a gentle cycle or by hand. No dryer. Dry flat. Air between wears; the fibre is naturally odour-resistant, so it needs washing far less often than cotton.
