Size (measured flat) Head circumference: Approximately 42cm (stretches) Height (when folded over the ribbed section): Approximately 23cm Material: 100% Acrylic This beanie, with a navy base and gold and white patterns, is perfect for winter. It's very warm because you wear the ribbed section doubled. We also have smaller sizes available, so you can wear them as a matching set. As this is handmade, we appreciate your understanding.
