Had one of these for about ten years then sold it... not a bad pack but it was heavy and bladder pocket was not useable. On the flip side, I carried some heavy loads with it.
If you are looking for an external frame that will haul anything, no matter shape, size or weight then this is the one for you. I have used it on float hunts and several backcountry camping trips in the wilds of Alaska with zero...
got my exo k3 last fall - been training with 50+ pounds for an elk hunt this fall. i've run it everywhere from a day trip deer hunting to 4-5 days worth of gear. Very versatile and user friendly.
anything mystery ranch in that size. i have the pop up 18 that is now discontinued. it is a small pack but works well for me because i only day hunt and usually run light on gear. the pop up frame on it is very sturdy and has carried 80ish pounds of boned out elk very well. all in all i am very happy with mystery ranch, wasn't excited about the price until i used it and now think they are worth it after owning it.
