Probably, though external frame packs mostly don’t exist any more. At least not in the normal consumer outdoor gear market (REI, etc). A fair chunk of the UL market forgoes a frame completely, and just uses some foam to add rigidity and padding. That’s usually for people going with a truly minimal base weight… Tarp tent, minimal quilt, possibly no stove (living off overnight oats and other things that can be consumed after soaking).
