Thank you for viewing. It comes with a padded liner that can be easily removed with a zipper. The liner uses "THERMOLITE," which has excellent heat retention, keeping you warm in winter, and can also be used as a light outer layer in spring and autumn when removed. The outer fabric is 100% nylon, a material that is resistant to stains and easy to handle. Size notation: The tag says "L 42-44," but this is an American size. It is a considerably large size, equivalent to XL to XXL (3L) in Japanese sizes (according to Gemini). Length from neck: Approximately 101cm Length from shoulder: Approximately 91cm Width: Approximately 63cm Sleeve length: Approximately 67cm As shown in the photo, the buttons are designed to be hidden when fastened.
