I am looking for a recommendation backpacks, specifically the kind that have stacked compartments. When my mom went around backpacking (35 years ago) around Europe (which is where I'm going) that's the kind she used and I've heard other people mention this kind, but I never seem to find any. I went around Central America with a top loading Northface that I do really like but it's just too big, I need to downsize. I'd like to check out the kind that I can get into easier but I only ever find top loading ones. Does anyone of a brand or anything to check out? Thanks!

I highly recommend these.
