Merino Wool Benefits

Say goodbye to the stereotypes you may have heard about old school wool, and say hello to super soft, comfortable, easy to care for Merino wool. Qualities like high insulation and low air permeability make Merino wool a performance favorite for outdoor apparel, socks and thermal base layers.

Machine Wash & Dry

Minus33 Merino Wool is also machine washable and dry-able, thanks to Total Easy Care technology. Developments initiated by Australian Wool Innovation and the Woolmark Company have delivered Merino Wool garments that are no longer hand-wash only. Learn all about caring for merino wool.
