Freeze-dried can be eaten without preparation, but would be a thirst producer and pretty bad for morale.
What do you think about DIY freeze drying? A minifreezer, thermormeter, hygrometer, vauum sealer, couple of hoses. ought to do the trick.
Others:
Apologies for use of brand names, including them to make reference easy to look up.
Single-person tent that is even lighter and less bulky
Hammock? Needs trees or shelving racks nearby to deploy, cozy sleeping, not warm.
Solo stove. Like a hobo stove, soda can stove, and pot combined in 1L volume.
Kelly kettle, similar but for fast economical boiling of water
Folding saw - there are the small fold out types for branches or small logs and the larger Sven saw type that can do the work of a full bowsaw, and then the even bigger buck saw
Pocket cable saw or pocket chain saw
Insect repellent - take that, dermatik! while active causes insects to flee (mass limit maybe?)
bear spray
camp chair - get a ‘got comfy’ morale bonus for crafting by the fire in your camp chair?
ferro rods - like flint and steel, only faster and less bulky
steripen , pocket portable water sanitizer runs on batteries
hand-pump water filter
dutch oven, aluminum and cast-iron
down sleeping bags, warm and compress very small/light
even lighter top-quilt, doesn’t cover head
high-tech sleeping pads like the thermarest neo-air. Comfort of a fur roll mat, at a fraction the volume and mass.
Camp light - basically battery powered candle. Light, small, dim, uses batteries very efficiently. Enough shady light to craft by if it is carried.
folding bucket - deploy to haul water, attach funnel etc.
camp shower - we have shave and a haircut, have (solar?) shower for morale boost. Water (hot) plus soap.
harmonica without stand, very small slip it in a pocket, play cowboy songs as the embers die down.
mouth harp, same concept.
lighter and smaller volume tarpaulin
can, pebble, string perimeter alarm
change the keffiyeh so it can be activated to toggle between head/mouth/head & mouth garb like a real shemagh.
down jacket
running out of ideas
lighter and higher volume backpacks
trekking poles- give a small speed boost and remove ‘bad knees’ while used in both hands
hiking stick, smaller boost but only one hand needed.
small water bottle or bladder that when worn around the neck at the normal or close to skin layer, contents don’t freeze
That’s it, I am taped out for now.
