LOL okay. Also fuck Amazon, and Walmart, and Kroger, and all the other national corporate chains. But that's who we have to work with unless you're lucky to have an independent outdoor store available with good selection of brands/models/sizes to test.
OP asked for a camping bag, I assumed backpacking as opposed to car camping as you can car camp out of a floppy duffel bag, but that will make a difference. For three days/two nights in the woods one could step up to a larger external frame bag which is infinitely more adjustable but will most likely end up with an internal frame bag. Which requires lots of trying on and fitting with a load in the bag. No internal frame bag is truly "one size fits all", or even "fits most", they fit the small size window they are designed to and outside that window is a sub-optimal fit.
For the common brands, Osprey and Arcteryx are great. Most people don't have that much to spend. REI's store brand is a solid alternative.
The tactical brands offer decent bags for holding lots of gear, but not for actual hiking or physical activity with them. If the intended use is to live in a truck and maybe cover a mile or two, sure they will work.
I love HPG, but their UTE pack is almost too universal especially with the floating shoulder harness. Kifaru is super nice and they send one to the dimensions you give them but you'd need to actually test fit one to know sizing.
Ever put in 5+ miles with a loaded pack that doesn't fit well? It SUCKS. I would take an Alice frame + large ruck over a poorly fitted internal frame any day, at least I know I can adjust an Alice to work.
So yeah, I could have gone deeper to ask OP his intended miles/day over what terrain, and height/weight/build, and gear selection, and stores available. Instead I gave a generic answer that would work for most people who actually plan to use a pack to camp from and put in some miles.
