Hi, Herew!
My basic survival kit for a hike around the parks and greenways where I live consists of the following:
Water (usually 2 - 24 oz bottles of Dasani)
Adventure Medical Kit "Pocket Survival Pak"
Beef jerky
Moist wipes
Dryer Lint (tinder)
SAK or Finnish knife
Adventure Medical Kit "Ultralight First Aid Kit"
Prescription meds to cover 5 days
Chapstick
Emergency blanket
Magnesium/flint stick
Cell phone
Extra batteries if using camera
All the items (except the water bottles) fit into a little "mini backpack" with a total weight of only 1.5 lbs. I love it!
