The Merino Wool Advantage

Merino Wool: Nature’s Technology.

Throughout history, people living in cold regions wore wool fabrics to keep warm. Their old style wool had fibers that were thick, 21 microns or higher, thus irritating the skin. That itchy wool will never be a problem again with the help from Minus33 Merino Wool. All of Minus33’s clothing is made from 17.5 – 18.5 micron fibers, thus creating a super soft, NON-ITCH feel.


At Minus33, we strive to provide you with an all-natural advantage on your outdoor adventures. We aim to deliver products with as high of a wool content as functionally possible to maximize all the wonderful benefits of this amazing fiber.

Merino Wool has plenty of natural properties that give you a distinct advantage over synthetic fabrics.
