Softer than cashmere and warmer than wool, qiviut is an ultra‑fine natural fibre woven from the under hair of the Arctic musk ox – a rare animal found in Alaska, northern Canada, Greenland and Siberia. Its hair can be harvested just once a year during the spring moult, meaning that only a limited number of garments can ever be made. Robert Gould, founder of Qiviut & Co, lived in Alaska for 20 years and in 2016 launched the brand’s debut product, a quilted jacket. An accessories collection now follows, offering a selection of knitted hats and reversible polka‑dot scarves, with prices starting from £119. Five per cent of proceeds from each piece sold will go to the Large Animal Research Station at the University of Alaska to fund studies into safeguarding the species’ continued survival.
