I've never paid any attention to where they are made, but I have packs made by Mystery Ranch, Gregory, and Osprey that are very good. I seriously doubt if they are made in either China or USA. There are some products that are simply not made here anymore.
Shoes for example, if you insist on USA made shoes you're limited to expensive custom-made footwear. Personally, I don't care as long as the quality is there and SOME products from China are good quality, SOME are junk. I've never seen any shoes/boots from China worth bring home, but the best hunting/hiking boots are made in Europe.
The "tactical" bags made a dozen or more pockets and covered with external webbing weigh more empty than I usually carry in my pack. I never use any of those features anyway. A quality pack designed for hiking with 1 main compartment and no more than 2-3 smaller compartments is what I prefer. Lots of good choices at REI, none at the shooting/hunting stores.
