And should have mentioned, my exo has two hip belts, i'm generally wearing a light jacket in that has two chest pockets and two hand pockets, and I wear a fanny pack. With all of that storage, I don't need an external pack in addition to that shown.
I use a LW Alpha with 4 sticks and use the stick talons. I hang my pack on the stand and have Molle shoulder straps and a kidney belt. Been running like that for ab 4+ years now and love it
