This is a Mackdaddy bag. It's a military-style bag that was very popular at the time. It has plenty of storage, and zippers are attached in key places, but the zipper pulls are made of rubber or plastic, and three of them have come off due to aging. I have the two that came off, but I've lost one. Also, one of the strings is damaged, as if it got caught on something.
