This pack has around 3000 ci of space. For me that is great for days, but I take more than most. For 5-7 days I would want a bigger pack. The MR Metcalf is 4000ci and the Marshal a massive 6400. I would look at one of these for a week trip. If I am out longer than a few days I take my Frontier Gear of Alaska Yukon (Barney's Pack). I could pack all my gear and my son of the mountain with that thing.I recently decided I'm going on my first elk hunt in 2021, a 5-7 day backpack hunt in CO. We'll have an outfitter pack an elk out if we kill one. Is this pack a deal that I shouldn't pass up, or should I shop around? I didn't know if this pack would have adequate capacity, but it does have the expansion feature...
