The CloudMerino 66 T-Shirt is constructed from 100% Merino Optimo wool jersey sourced from Japan, delivering a silky-soft hand feel alongside natural thermoregulation and moisture management across varying conditions and seasons. The regular fit suits a wide range of activities, from trail use to everyday wear, while a raw hem construction at the top reduces friction points and keeps weight minimal. An exterior detachable care label ensures nothing contacts the skin unnecessarily, reflecting the shirt's focus on all-day comfort.
