I love my Exo 3500. I also have a Kifaru Tactical Frame with a Nomad 2 bag that I use for really heavy bulky loads, but the Exo is my choice for most hunts. All deer hunting and most other hunting I'll choose the Exo. I love the bag lay out and how easy it is to keep organized and get glassing tools out with a fairly minimal design. I like that I can put my rifle in the side optic pocket too when hiking in the dark when I don't need quick access to it. Very nice design.
