Do I really need long sleeves in the heat?

Yes. It is not just for the sun, but for the mosquitoes and razor-sharp jungle vegetation. You will be cooler in loose, breathable long sleeves than in a tank top with hundreds of bites.

How do I keep my clothes dry?

Pack items in vacuum-seal compression bags. They save space and create an airtight barrier against the constant dampness of the rainforest.

How to Pack for the Amazon Rainforest

Focus on moisture-wicking synthetic fabrics and full coverage to protect against insects and humidity. Pack 3 complete outfits of long sleeves and pants, and plan to wash them frequently rather than overpacking.

Select your base layers. Bring only long-sleeved shirts and long pants made of lightweight, quick-dry synthetic material. Avoid cotton at all costs; it stays wet for days in 90% humidity and will grow mold if left in your bag.
Prioritize insect protection. Choose light-colored clothing (khaki, tan, or grey) as dark colors attract biting flies. Ensure all gear is treated with Permethrin spray before you leave home to repel mosquitoes and ticks on contact.
Manage your footwear. Pack one pair of broken-in waterproof hiking boots and one pair of lightweight trail sandals for the lodge or camp. If visiting during the wet season, bring tall rubber boots (often provided by lodges, but check ahead).
Seal your electronics. Place all cameras, batteries, and documents inside individual heavy-duty Ziploc or dry bags. Humidity will kill electronics and ruin paper passports within 24 hours without a seal.
