Cold machine wash gentle cycle every 2–3 months of heavy use, or spot-clean with mild soap. Air dry in shade (direct sun lightens color over time). Avoid: bleach, fabric softener (coats the fiber and reduces breathability), tumble drying on high heat, ironing directly on printed surfaces. For leather trim, condition once a year with neutral leather cream. Properly cared for, a hemp bag lasts 10+ years and softens into a patina most buyers prefer to new.
