This is the Montbell Exceloft Thermaland Cap. It has a sturdy nylon fabric, boa fleece, and inner padding for excellent cold protection. It's very warm, but my ponytail didn't fit well, so I've only worn it once or twice, and the condition is good. Size: S-M 57-58cm The foldable brim is convenient. The lining is made of Chamois, a lightweight and soft fleece material. It has a three-layer construction using water-resistant materials. Faux fur is used on the ear flaps. Mesh fabric is used in the center of the ear flaps. There is an adjustment tape at the back. I will ship it compactly.
