i wouldn't buy an eberlestock pack without a scabbard, even if you aren't a gun hunter. i put my tripod in there, fishing rod tube, whatever. thats the beauty of those packs. the only concern i might have is the weight of it. they are known for being a little heavier than others. i am talking in general though, not about the one you're asking about specifically.
i have an x1 and love it.
