More on Merino: Our merino is made using the Schoeller EXP method. EXP stands for “EX-Pollution", which describes its avoidance of pollutants during the anti-felting treatment process. The merino yarn used to make this fabric is GOTS certified.
Merino jersey that is considered "easy care" (can be laundered without fulling) is traditionally processed with the use of chlorine and often coated in a polymer (plastic) finish.
In contrast, the EXP method uses salts to keep the wool ecological.
