I have been doing some solo scouting trips/ gear shake trips for elk season. I skip the tent in favor for a bivy sac and light weight tarp. I do not bother with cooking anything. So no stove and all of that crap. I go high calorie walnuts, dried fruit, salami and a flask. Taking starbuck vias are helpful as they dissolve in cold water and keep up the kick.
I was pretty stripped down and still felt a bit overpacked, but when hypothermia is a potential issue I grin and bear it because it is a no brainer. That said, I found super light weight down pile throw blankets at costco 20$. They are light as *censored* and super warm! I was able to really cut back on the extra night cloths I would normally take and just bundle up in the blanket, and with that dropped prolly 5# maybe more.
I am just leaving more and more stuff in the car in case of a double pack out, but still trying to find the right balance.
What type of packs do folks use?
