I have an OC bag that I got in 75 I had to replace the strap but it’s still a good bag.
Down side is it it’s just a little bigger then my wedge tent. When full of all the stuff I planned for it it was a load for a small horse. We don’t see bags it’s size from the old days.
Howsomever there is nothing wrong with the super quality of their bags. And I’ve bought a smaller bag from them some years ago was just as well made, and I expect it to give good service for years to come.
