So after tons of research and reading forums and reviews I’ve decided to go with the EXO K4, I just need to decide if I go for the 3600 or 5000. I am wanting a pack to use for backpacking AND hunting. 99% of the time backpacking trips will be less than a week with the wife and hunting will be drop camp but with occasional spike camping for a day or two with my buddy. The weight difference is minimal and the price is only a $20 difference. Is the 3600 enough room? I currently use the Eberlestock Team Elk to hunt so either is a big step up in quality and size.
