This is my second AT6 High Sierra.
Best points:
Spacious
Lots of pockets
Solid construction
Fairly inexpensive
Very durable
I bought both of these to carry cases of wine on flights which I do frequently. They both are loaded to 70lb, the airline maximum on each flight. The older one, three years old now, looks new. I am very happy with the purchases and would do it again if eitehr of these ever wears out.  My other bags Tumi, Victorionox, TravelPro are not as durable as are these.
