This beanie is 10 inches tall and has an 18 inch diameter but can comfortably stretch to 26 inches and fits any adult. It is hand-dyed a deep forest green with gold highlights, reminiscent of Ginkgo leaves in autumn, and hand-knit from a super soft and glossy Merino wool, baby Alpaca, and Mulberry silk blend. This one of a kind accessory should be hand-washed in cold water and air dried.
