In high country September weather, I have my 10 day pack under 40 pounds - right at 39 actually running a Kifaru Mt Hunter. That's with bow weight, food, 2 L water, and clothes I'm wearing included. Considering a move to SG to save another several. I won't lie though, there are nights that ain't too comfy and when your clothes get wet...well, they're wet. Start somewhere though and spend money smartly to clip away at your pack weight - justify costs where the most ounces are shaved. Finding items that pull double duty is also a quick way to shave weight. I.e., trekking poles that also replace your tent poles OR half a vehicle's reflective sunshield that doubles as butt pad for glassing and insulation/padding under your feet for sleeping.
