This yarn is a breakthrough multi-season wool yarn, made from a blend of Australian superfine Merino wool and eco-friendly recycled polyester. The wool's natural crimp and high moisture absorption create a dynamic temperature control system. It quickly absorbs sweat and keeps the skin dry and breathable in humid conditions, and regulates body temperature in changing climates. The wool also contains aromatic amino acids that absorb UV rays below 300nm, providing natural sun protection. The addition of recycled polyester enhances the yarn's strength and wear resistance, giving the knitdown excellent wrinkle resistance and maintaining its crisp shape even after prolonged wear.
