Thank you for viewing. This is a camera bag pack from PGYTECH. I used it a few times, but I'm selling it because I couldn't fit all my equipment. I haven't used it in places where it would get dirty, so the condition is quite good. It protected my camera equipment without any problems, so I think it's a good product. There is no sub-bag. Please understand that no claims or returns are accepted after purchase. Negotiations are possible, so please feel free to contact me.
