Vintage The North Face Hiking Backpack Hard Back 20x13x8

This North Face hiking backpack appears to be vintage. It features only one main compartment with one small zipping pocket inside. There are no front or side pockets. It has a hard shell back and waist support bands with large buckles. There is some sun bleaching on the nylon fabric. The only measurement on the bag is the label regular. I measured the back at 20 and the bottom at 13x8, but when stuffed full, it would clearly expand past that.
