This is a sub-bag from F dash Familia. My daughter used it for several years when she was little to go to piano lessons. It's made of vinyl, but it's sturdy because there's a cushion material in between. I think it's easy to use even on rainy days. There are two pockets inside. There is also a zippered pocket on the outside. There is some fading on the corners, but there are no scuffs on the bottom. How about using it as a lesson bag or sub-bag? Thank you.
