Zombie Apocalypse. It may seem unlikely, but studies have shown that it can actually be a threat to humans. Whether it happens or not, you should be ready.
Rifle with Ammo - to kill zombies but to also harvest game for food and for protection against gangs. I prefer a .22 because its a lightweight, inexpensive main weapon with dirt cheap ammunition |  Not a .22, but you get the idea |
Backpack - to hold everything you need to bring along, should be lightweight and have many pockets |  |
Sleeping bag - lightweight, but warm |  |
Rope - about one hundred feet, for pitching a tarp tent, tieing things down, climbing, and more |  |
Tarp - 8 by 10, to make a tent, collect rain water, and for signaling |
First Aid Kit - to tend to wounds you get, preferably in a water-proof bag |
Self Powered Flashlight/Radio - to see in the dark and to keep up on recent event (if radio stations still work) |
Local Maps - to take safe routes and not get lost, and finding sources of water. |
Compass - to go with the map, know what direction you are heading |
Red Glow Sticks - if your flashlight fails you and you really need light, plus red light doesn't affect your ability to see in the dark like other lights |
Garbage Bags - at least a dozen, can be used for human waste, as a poncho, keep clothes dry, and more |  |
Pocket Knives - at least 2, for endless uses |  |
Multi-Tool - usually include needle-nose pliers, knife, screwdrivers, bottle and can openers, file, and wire cutters |  |
Axe, Hatchet, or Machete - Can be used for their original use and also against zombies |  |
Baseball Bat - classic zombie-skull crushing device, fairly effective for close-quarters |  |
Fire Starting - waterproof matches and a flint-and-steel work fine. Other options include Bic lighters, Zippos, etc. To start fires for warmth, cooking, signaling, light, and more |  |
Water - I would suggest refilling a plastic soda bottle with water, but if that is too heavy, then either a stainless steel or a plastic water bottle will do. You eventually WILL have to refill, so also bring along chlorine tablets or something to boil water in |  |
Dehydrated/Freeze-Dried Food - includes Ramen noodles, canned goods, granola bars, beef jerky, peanut butter, etc. Make sure you replace them before the expiration date BEFORE the apocalypse |  |
