One quick tip for “Packing for Fieldwork”: Pack your clothes in a sealable bags (or waterproof packing cubes) before packing them in suitcase/backpack. This will prevent your clothes from getting dirty/ wet if accident happens. Divide them into few sealable bags will be best. Then, you can also differentiate dirty vs clean clothes when you are in the field.
Once, I fell into a river, but because my clothes are in sealable bags, I still have dry clothing for fieldwork.
