I don't know what model backpack it is, but their frame really let me down in archery season, and they refused to even send me the part that broke, in spite of their "lifetime warranty". I packed a front elk quarter, the first time I had ever used the frame. In one trip, one of the brackets holding the meat shelf broke. I contacted Kelty and after a bureaucratic runaround, they wouldn't even send me the replacement part so I could fix it myself. I will never recommend their products.
