Size 58 (M) Brim length: Approximately 4cm Height: Approximately 14cm Made of cotton fabric, but with a felt-like texture, it's perfect for the coming season. I received this from a family member who was decluttering, and it's in good condition and seems usable, but the size doesn't fit me, so I'm selling it. The brim will not be folded for shipping, but I will make it somewhat compact for shipping.
