I bought this about three years ago, but I haven't had many chances to wear it, so I've been storing it. It's a sturdy wool hat. The lining is fleece, so it won't feel scratchy against your skin. It's one size and doesn't stretch much, but I think it should fit people with an average head size. 80% wool, 20% nylon Lining: 100% polyester (fleece material)
