2 spare pairs of goggles
2L gatorade
1 large pack beef jerkey
6 granola type bars
4 energy drinks(great calories if you have to spend the night)
gps
2 way radios
another 50ft of rope(needed it for something else this spring)
and a few other odds and ends that i can't remember right now
i will split some of this up and put into tunnel bag for ease of use, but all survival gear stays in pack, along with extra rations and fluids
