Should I pack more clothes for longer trips?

No. Pack the same amount whether you're going for 1 week or 3 months. You'll do laundry every 2-3 days regardless of trip length. More clothes just means more wet, smelly luggage.

What about cotton shirts - aren't they more comfortable?

Cotton feels great when dry but becomes a soggy, smelly mess in humidity. You'll be damp 80% of the time, so synthetic or merino wool that dries fast and resists odor is much more comfortable overall.

How do I keep clothes from getting moldy?

Never pack wet clothes. Use ziplock bags to separate damp items and air everything out daily. Pack antifungal powder and use it in shoes and on clothes if staying in humid accommodations without good airflow.

Do I need special socks?

Yes - merino wool or synthetic hiking socks that dry quickly. Cotton socks stay wet all day and cause blisters and fungal problems. Change socks twice daily and always pack extras.

How to Pack Clothing for Humid Tropical Climates

Pack lightweight, quick-dry fabrics like merino wool and synthetic blends. Bring 3-4 days worth of clothes and plan to do laundry frequently. Skip cotton except for underwear, and prioritize breathable materials over waterproof gear.

Choose moisture-wicking base layers. Pack merino wool or synthetic blend t-shirts and tank tops. These dry in 2-3 hours versus 8+ hours for cotton. Bring 3-4 shirts maximum - you'll be washing every 2-3 days anyway.
Pack one pair of quick-dry pants. Bring lightweight hiking pants or travel pants in synthetic fabric. These work for temples, nice restaurants, and air-conditioned spaces. Skip jeans entirely - they take forever to dry and feel miserable when wet.
Bring 2-3 pairs of shorts. Pack above-the-knee length in quick-dry fabric. Longer shorts dry slower and shorter ones may not be appropriate for temples or conservative areas.
Pack cotton underwear only. Cotton underwear is the exception - it's more comfortable than synthetic in humid heat. Bring 5-6 pairs since you'll change twice daily. Pack in ziplock bags to keep dry.
Choose the right footwear. Bring quick-dry sneakers or hiking shoes, flip-flops, and one pair of closed-toe shoes for temples. Avoid leather - it gets moldy. Your feet will be wet constantly, so prioritize shoes that drain and dry fast.
Pack a light rain layer. Bring a packable rain jacket or poncho, not for staying dry (impossible) but for wind protection in air conditioning. Skip umbrellas for walking - you'll sweat more carrying one than you'll save from rain.
