Sourcing possum-merino-silk knitwear from two of the most creative, yet with a good eye for function and longevity, knitwear specialists, KoruNZ and McDonald Textiles.
KoruNZ's mix is the optimum 40% possum, 50% merino and 10% silk, and the fabric tends to be a bit denser.
McDonald's mix is the sumptuous 35% possum, 55% merino and 10% silk and the fabric tends to be a bit lighter. Not much though.
Try beating possum-merino-silk for warmth. Unless the polar bear is lying flat out on top of you. And (sic) that, we wouldn't want.
