Essential items to pack in your travel backpack
Passport: Your most important travel document should be stored safely away from wandering hands.
Clothes: Try not to overpack. Instead, work with light layers and warm layers—quality clothing.
Underwear: If you're traveling in winter, thermal underwear works wonders! Otherwise.
Water bottle: Out in the field a fresh water supply is vital.
Medicines: Travelers taking prescribed medicine should make sure they have enough to cover the duration of their trip.
Travel guide/phrase book:These days there's an app for everything, but it's worth packing a phrase book.
Hat/cap: An obvious item to pack to keep you shaded when necessary.
Backpack rain cover: Some backpacks incorporate a fold-out rain cover.
Padlock: For peace of mind, pack a couple of padlocks.
Running shoes: A well broken in pair of running shoes is a must-pack travel item.
