Things to Bring to the Peace Corps
1. Ziploc bags.
2. Nalgene.
3. Quick dry towel.
4. Hand sanitizer.
5. Deodorant.
I use all of these things literally every day and have been unsuccessful finding similar, cheap versions in country.
This is good advice for any trip like this. I used all of the above in Tanzania in a few clutch moments. Also, headlamps and baby wipes.
