I have been using for many years and very much like an Eberlestock X2 day pack. It is built solid, I carry a full size spotter and tripod in the long side pockets, and it has nice capability to carry a full size elk quarter out.
It is a bit heavier than other day packs, but it fits so well and snug to my back that I don’t notice it.
