This is the bison gear I picked up off ebay. Not really crazy about the 2 compartment model, as the bottom one is harder to get into when the top is full. My brother has a different model that would be the same size as mine, but it’s a single compartment. I’d rather have that. Mine came with an integrated game bag in the top compartment, which I cut out. It has shoulder straps and two small pockets on the waist belt. The two vertical pockets on the side are removable, but made a great spot for multiple thermacells on bear hunts. Sits well on the hips and shoulders when loaded. If you’re ordering one new, I would have him put more quad lashing points on it than you think you need. It has two on the top and two on the front of the bottom compartment. I’m going to put two more on the front of the top compartment and two on the bottom of the pack. With nylon straps you could lash whatever you need to the outside (rain gear, extra coat, camera arm, double bull seat etc.). The pack is heavy on its own, so it wouldn’t work well for a fly in hunt where weight mattered. I would prefer a single compartment that may be deeper, and use smaller zippered pouches (or ziplock bags) inside that, to separate gear for easy access. This size works well for whitetail / bear / tree stand hunting. I have a Rubbermaid tub full of packs that looked good but didn’t work as well as I’d hoped. The bigger they are the more useless crap you put in them anyway. This pack is quiet too, which is probably the most important quality to have. I have a pack that almost cost me a mule deer in Montana because some of the components squeaked when I was on a stalk. Hope this helps.
