A Backpack, Hiking Boots, Secret Pockets, Pouch Pockets
Incidentally, one of the reasons why the entire world is peopled with operatives, operators, soldiers, special forces, recon, and spies dressed like eco-tourists and dirty trustafarian hippy backpackers is purely practical: you get to wear the same gear as the Lurps. Effectively, jungle boots, jungle "day" packs, water, cameras, "guide books," notebooks, tropical fatigues from LL Bean. Thanks primarily to R.E.I., the typical tourists is better provisioned than a Navy S.E.A.L.
