Raw, untreated wool has scales that make it itchy and coarse and cause it to shrink, so most wool fabrics are treated with chlorine to reduce the scales. But chlorine is a pervasive pollutant that’s especially harmful to organisms living in water and soil. We remove the scales from our merino wool fibers using a unique chlorine-free process that’s bluesign® approved.
