I had a Bora 80-two of them actually; one I got on eBay and it was too big and one I got new.

This pack is very well made, heavy, expensive and for me, not comfortable at all-the waist belt was super stiff and didn't fit me right. I even tried one on in REI and thought it was okay, but I was wrong.

I got rid of both of them and got an old Kelty Flight from another member. Way better for my needs-I think it is about 4000 ci or so and very comfortable.

The lesson here is that comfort and heavy do not necessarily go together. If I was buying another big pack, I'd probably buy something from Granite Gear-they seem to fit me fine.
