This is a helmet bag, a collaboration between Anatomica and Porter. I purchased it 1-2 years ago. I used it for commuting, so there are small scratches and stains. The size is 43cm (height) x 43cm (width) when laid flat. It has a large capacity and can be worn over the shoulder, making it a convenient bag. #Porter #Anatomica #anatomica #porter #helmetbag Color: Green Material: Nylon Features: Has a gusset
