Credibility level: I was a Peace Corps Volunteer in Mali
  1. Headlamp and batteries
    Get a Petzl. When you don't have to hold and point a flashlight the whole world is your oyster
  2. Surge protector/converters
    If your destination has inconsistent electricity, surge protector is helpful for your devices
  3. Reading material
    Some that doesn't require electricity
  4. Camera
    Consider if this is the time you've been waiting for to *actually* learn to use that dslr you bought last year
  5. Snacks
    Lots. For flights and for times you can't find restaurants or street food.
  6. Sunblock
    Lots if you're headed to the hotter adventure destinations. Usually very expensive in the developing world and they won't have the kind you like. Protip: get the alcohol based spray kind; it's lighter weight and won't clog pores as much.
  7. Hand sanitizer
    And toilet paper too.
  8. Face wipes
    If it's dusty it's really nice to have a face wipe to use when water isn't easily accessible. I like the neutrogena grapefruit ones.
  9. First aid kit
    Bring everything. Band aids, neosporin, wound wipes, hydrocortisone, tape, gauze.
  10. Med kit
    Advil, Benadryl, cipro (easy to get over the counter in developing world), Imodium, flagyl (for parasitic infections, also easy to get over the counter in developing world), NyQuil, DayQuil
  11. Birth control method
    Depends on where you are, might not be easy to find
  12. Vitamin c
  13. Tampons
    Expensive or simply UNMENTIONABLE
  14. Bleach or iodine
    For purifying water. You can't use iodine for more than 2 weeks without risking thyroid imbalance, so use bleach if you're traveling for awhile. Also I think the bleach water tastes better than iodine water
  15. DEET/malaria prophylaxis
    Don't fuck around with citronella oil if you're in malarial endemic areas. Ask for malarone for malaria prevention, not lariam.
  16. Laundry detergent
    Bucket laundry, baby
  17. String
    Clothesline, belt, shoelace, emergency repair materials
  18. Duct tape
  19. Water bottle
    Carry at least 2L of water bottle capacity. If you're in the equatorial region you need to be drinking 3-5 liters a day.
  20. Ziploc bags
    Water proofing can be useful
  21. Pocket knife & bottle opener
  22. Passport
    Take a photo of your passport and put it in drive or Dropbox in case you lose it. Also don't carry all your IDs and credit cards in the same spot
  23. Print out of itinerary, receipts, map of destination
    In case you have a tough time finding Internet access
  24. Appropriate clothes
    Research what's right for your destination to be respectful and safe
  25. Big scarf or piece of fabric
    For sitting on when there's nothing clean to sit on
  26. Unlocked phone
    You can buy local SIM cards and minutes easily in most parts of the world
  27. Mosquito net tent
    If in a malarial zone get yourself a REI bughut tent. Easy to put up anywhere
