Universal Principles
Pack light: Asia’s laundry is excellent and cheap. You don’t need 2 weeks of clothes.
Layer over bulk: A light layer for air conditioning is more useful than a heavy jacket (except Japan in winter).
Respect the culture: One temple-appropriate outfit saves renting sarongs repeatedly.
