1. Water filter - Without water you can only last 3 days, so having a way to filter your water is crucial. The last thing you want to do is get sick during a survival situation. Remember not all water filters remove viruses see contaminant size chart here.
2. Canteen w/ Cooking Cup - Once you find water you are going to want a way to take it with you, having a canteen with a cooking cup not only lets you do just that but also gives you a back up water purification method.
3. Survival knife - Having a good knife will help you build a shelter, clean game and even hunt for food plus provides minimal protection if needed.
4. Fire starter - Having a way to build fire can not only save you from hypothermia but is also lifts your moral. You should always have at least three ways to make fire.
5. Multi-Tool - Sometime you need more than just a knife, having a good multi-tool may let you do some things where a knife just won’t do.
7. Hatchet - Having a hatchet will come in handy for building shelters, splitting firewood, protection, and cutting or digging through snow or ice.
8. First aid kit - Having a good first aid kit is mandatory if you spend anytime outdoors. If you go with a pre-packaged first aid kit, be sure to include these items. Dermabond to use for wound closure, some QuikClot to stop bleeding and a venom extractor kit for snakebites.
10. Compass – Having a compass and some good navigational skills, you may just be able to find your way back to civilization. Some models come with a built-in magnifying glass used for zeroing in on map details, but may also be useful for starting a fire, removing splinters and insect stingers. Some also come with sighting mirrors that can also be used for signaling.
