I'm sure Mr Founder (sir) knows that his backpacking list is missing a few heavy hunting items like:
*Weapon/ammo/tools
*Butchering gear: game bags, bone saw, knife sharpener etc
*First aid/trauma kit (no little stuff like band-aids, yes blood clot stuff for really bad bleeds, yes airway, yes antihistamines) ect.
*Water purifier
*Work out a way to have trecking poles, scope tripod, camera tripod, and rifle pod all be the same single item.
Might save weight with the phone/camera/gps being one unit.
Concur on the 2-days w/o stove but I end up carrying too many powerbars instead. I love my JetBoil.
Does sphagnum moss grow where you're going? You might not need disposable paper at all...
Never had any luck with solar showers.
