I'm looking forward to the Comfort section of the article.
I remember when I first started trying on packs (incorrectly, I might add) I had no idea what was considered "comfortable" with 10, 20, 30, or 40 lbs on my back.
Sure, some packs felt better than others, but what was it SUPPOSED to feel like? Even today, I often wonder how what I consider to be comfortable compares to what everyone else considers comfortable.
I've got 3 packs. SMD Swift, Osprey Exos and Osprey Talon. Yes, they're all "comfortable" to me and I can spend all day in them with a loaded pack, but there are so many other packs out there, that how do I know I'm nowhere near as comfortable as I could be with a different pack!? I need to try ULA, MLD, Gregory, REI, Cilo, Granite Gear, and the list goes on. But time and $$ prevent that from happening.
I'm rambling now.
