Should I bring a rain jacket?

In hot, tropical climates, a standard rain jacket will just make you sweat profusely. Bring a high-quality, lightweight rain poncho or a simple umbrella; they provide airflow while keeping you dry during sudden downpours.

How do I keep my clothes from smelling in the humidity?

Pack a few dryer sheets or a small sachet of silica gel in your packing cubes. Always hang your clothes up immediately upon arrival to ensure they air out, rather than leaving them in a cramped bag.

How to Pack for Backpacking in Hot Climates

Stick to lightweight, moisture-wicking synthetic or merino wool fabrics and limit your wardrobe to one week of clothing regardless of your trip length. Use a 40-liter backpack and packing cubes to keep your gear compressed and organized for humid environments.

Select the right base fabric. Avoid cotton, which holds moisture and stays wet. Pack merino wool or technical polyester blends that dry within two hours and pull sweat away from your body.
Limit your quantity. Bring 5 t-shirts, 2 pairs of lightweight shorts, 1 pair of long, breathable hiking pants for temples or protection from insects, 7 pairs of underwear, and 5 pairs of socks. Do not pack more than this; you can wash clothes at local laundries for $1–$2 per kilo.
Organize with compression cubes. Use compression packing cubes to reduce the volume of your clothes by 30%. Keep your 'dirty' laundry in a separate, breathable mesh bag to prevent odors from spreading to clean items.
Layer for versatility. Pack one lightweight, long-sleeved UPF-rated shirt. It protects your skin from aggressive sun and acts as a barrier against mosquitoes in the evening without causing overheating.
