Women's XS size (New Zealand size) Material: 65% Merino Lamb Wool 25% Possum Fur 10% Silk Merino lamb wool is wool shorn for the first time from lambs of the Merino breed, about 6-7 months old. It is characterized by its supreme softness, suppleness, and high heat retention. Possum fur is a natural material obtained from possums in New Zealand. It has a hollow structure, making it very light and highly insulating.
