Eagle Creek Travel Backpack
It has an internal Aluminum frame (see close-up pic).
Backpack and wide hip or waist straps fold down and are zippered in for carrying with handle. Either top side (although that handle shows signs of wear with a crack in the plastic and perhaps had been taped) or
convertable to Carry-on for airplane with a handle duffle style.
Extra large capacity. Can strap a sleeping bag below with straps in place.
Lots of heavy plastic D rings , Fastex fasteners all in good shape.
This has been used, but has lots of life left. My boyfriend got it for me, but it is just to big for me (5'4")
