Our Fabric Weights

4 different fabric weights gives you plenty of options for year-round wool wearing. Merino sheep's coats have naturally adapted over time to help them survive in many extreme environments. Wool is great as an insulation tool, or to help block the sun and wick moisture away.

Learn which weight is best for you.

Why Choose Merino Wool?

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 have now made merino wool a performance favorite for outdoor apparel, socks and thermal underwear. 

Machine Wash and 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.
