This is a Montbell body bag/waist pouch. I'm not sure of the details, but it's a collaboration with DOC JAPAN. It was at home, and since no one in the family uses it, I'm putting it up for sale. It's new and unused. I will list the size, but please note that these measurements are approximate. Please use them as a reference. (Size) Height: Approximately 14cm Width: Approximately 26cm Depth: Approximately 6cm (Color) Khaki STYLE#1123764
