Should I bring a rain jacket?

In the tropics, a heavy rain jacket will make you sweat more than the rain itself. Bring a lightweight, breathable poncho or a small travel umbrella instead.

How do I stop my clothes from smelling musty?

Humidity is the enemy. Always pack a few cedar balls or silica gel packets in your suitcase. If you have worn clothes, keep them in a dedicated 'dirty' bag with a dryer sheet until you can wash them.

How to pack for a humid tropical climate

Prioritize loose-fitting, moisture-wicking natural fibers like linen or lightweight merino wool to allow airflow. Stick to a 'capsule' system of 5-7 days of clothing that you can wash and air-dry overnight.

Select your fabrics. Avoid heavy cotton or denim, which retain moisture and take days to dry. Choose linen, hemp, or performance synthetics designed for high-heat activities. These breathe better and dry in under 6 hours.
Apply the 5-7-10 rule. Pack 5 tops, 3 bottoms, 1 light outer layer for air-conditioned spaces, and 10 pairs of underwear. This is enough for a week; wash everything in a sink or local laundry shop mid-trip.
Use packing cubes for airflow. Pack items using mesh-front packing cubes. This prevents moisture from getting trapped inside your bag, which can cause musty odors in tropical humidity.
Protect against the elements. Include one long-sleeved, lightweight button-down shirt. It serves as sun protection, insect barrier, and complies with dress codes for temples or formal dinner spots.
