This is the Leh classic Kesa 袈裟 bag. This season, the designer added a gimmick to the bag that originally had a storage capacity. A long zipper is attached to the handle, and Tyvek fabric is used for the thin separate cloth inside. Folded like a bag. If you turn it over and insert the main body of the Kesa bag as it is, it transforms into a larger laundry bag or protects it from the rain.
A mix of polyester, cotton and linen
Gentle wash in cold water. Do not put it in the dryer.
