I run Nimrod modular pack. They make packs in usa for firefighters and models for hunters. They where first for rifle and bow carry years ago. I also have the alum, pack frame that I have used on elk and moose. I carry meat duffle on my longer hunts and always take load on way out. I carry bow and rifle opposite so I have packs for each and double bow hooks on that pack for purpose. I also have QD buckles on the shoulder D rings for bino carry.I still hunt alot grizz area so I do not use the rifle carry they have, I am a front carry military style,hand free for climbing and glassing.
