According to Wired magazine in the United States, many outdoor enthusiasts are eager to find a survival backpack that can help them in emergencies. The outdoor survival tools mentioned here are all compact items that can be packed into a small bag and carried around, making them convenient for wilderness trips. Of course, GPS and satellite phones are essential portable items, but the tools listed here are affordable outdoor gear—especially useful when GPS or satellite phones fail or are unavailable.

    1. High-calorie protein bars

    Hunting and fishing are labor-intensive and not very cost-effective. The calories you burn searching for prey often outweigh the energy you gain from eating them. Therefore, bringing some snacks can save you the trouble.

    2. Flashlight

    Search and rescue teams can spot a flashlight beam from a great distance. It’s one of the best ways to attract attention to yourself and is easy to carry. If you have trouble starting a fire, a flashlight can come in handy.

    3. Whistle

    When you’re lost in the woods, a whistle is the best tool for signaling for help. Blowing a whistle periodically requires much less energy than shouting, and the high-pitched sound carries farther.

    4. Backpack hammock

    Protecting yourself from natural elements in extremely hot or cold conditions—such as avoiding wind chill and rain—can make a huge difference. You can also set it up to create a more elaborate and comfortable shelter.

    5. Water purification device

    Drinking impure water does more harm than good. By properly filtering and purifying it, you can avoid many health risks.

    6. Plastic garbage bags

    Plastic garbage bags are thin and lightweight but incredibly versatile. You can use them to collect rainwater, cut three holes to turn them into makeshift rain covers, or use them as windbreaks for your shelter. Bring a few—they’re surprisingly durable.

    7. First aid kit   

    Getting seriously ill is more troublesome than getting lost. Your first aid kit should include supplies for treating major injuries, not just cuts and scrapes. Bring Quick Clot or Celox for severe bleeding, along with tweezers, needles and thread, antibiotic ointment, sunscreen, and any other specific medications you might need in an emergency.

    8. Metal cup or can

    Drinking water is more important than eating food. With a metal cup or can, you can boil water to kill bacteria and ensure it’s safe to drink.

    9. Butane lighter

    Starting a fire with flint is relatively easy in dry conditions, but in wet weather, you’ll need a lighter and some kindling to help get the fire going. Wax-coated cotton balls and a small bottle of Bacardi rum are both viable options.

    10. Knife

    You shouldn’t leave home without a knife. A sturdy knife is an essential tool for building shelters, preparing food, starting fires, and countless other tasks.
