There is no material listed, but this hat has a crisp feel, like a linen blend. The multi-colored knit pattern adds a nice accent to simple outfits. It has a slight stretch and can be worn without feeling tight. Size (flat measurement): Length: Approximately 15cm / Width: Approximately 25cm Condition: There are fold lines, but it's almost like new with very little wear. Please refrain from purchasing if you are concerned about minor details, as it has been stored at home. It will be folded for shipping. Thank you.
