Ecopossum™ is an exclusive blend of fine Merino wool, luxurious Brushtail possum fibre and silk. The stunning combination of Merino and Brushtail possum fibre creates featherweight softness and outstanding wearing qualities. Ecopossum™ yarn is unique in that it feels cashmere soft and is incredibly warm, yet it will not pill (rub). This is due to Brushtail possum fibre having a hollow structure and no scales. Air is trapped both within the fibre and in the fabric when blended with high crimp, fine Merino, creating a soft, lightweight, and exceptionally warm garment that has very high performance and durability characteristics. Ecopossum™ garments also wash extremely well.

Ecopossum™ yarn was first developed by Snowy Peak Limited (the parent company of Untouched World™) in 1992, the first new natural fibre to be used in a textile in over 100 years. All garments made from Ecopossum™ carry an assurance of quality from forest to finished garment, and a guarantee of essential fibre selection and processing controls.
