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. All of our baselayers are made from 100% Merino Wool so you can be 100% Prepared for anything.


We’re in the business of making adventure possible.
