Our premium linen cap is designed for daily use. Italian linen is resilient and provides breathability to keep your head cool in the summer. Use a tape measure for accurate sizing: Small (54.5 - 56.5 cm), Medium (56.5 - 58.5 cm), or Large (58.5 - 60.5 cm). To maintain its quality, clean the cap with a damp cloth. Never use a washer and always hand wash your linen cap.
