Our fine merino wool is shorn from Australian sheep, who stay warm in the face of temperatures as low as five below zero. As a lightweight, natural fiber that's evolved to protect against the cold, it adapts to your body's temperature allowing you to never feel overheated. And its natural moisture-wicking properties keep you dry in the sun when transitional temperatures can be unpredictable. Spun by one of Italy's premiere yarn suppliers, Tollegno, producing incredible quality and longevity, this merino sweater is superlatively made for you.
