Boots

• A sturdy pair of jungle boots is a must if you plan to embark on a journey through a tropical rainforest. Jungle boots have specially designed soles to repel mud clumping and the uppers are made out of nylon and canvas to keep your feet cool. Avoid standard hiking boots at all costs as they tend to clump up with mud and get unbearably hot.
  
  

Shirts

• While short-sleeved shirts may keep you a little bit cooler, long-sleeved shirts are the way to go. You need long-sleeved shirts to not only protect your skin from bug bites but also to shield your skin from the sun's rays and poisonous plants. You should also select light-colored shirts to keep you cooler and select shirts that have multiple pockets.
  
  

Hats

• Wide-brimmed hats are not only common but almost a necessity. Not only do they keep your face well-shaded but they also protect your head and face from poisonous and prickly plants of all kinds. You should also think about getting a protective netting to hang around the brim of your hat to keep mosquitoes and other bugs off of your face. If you're unsure about whether you want a cotton or straw hat, note that straw hats are stiffer and thus better protect your head and face from plants. They are also easier to attach protective netting.
  
  

Poncho

• Because it rains several times a day in the tropical rainforest, having a poncho to repel water from leaking onto your clothing will be a huge advantage when trekking through the rainforest. Getting wet is inevitable due to the heat and humidity, but you can limit the degree to which you get wet by investing in a poncho that can easily roll up into a pouch in your backpack.
  
  

Socks

• You will need thick, cotton or wool tube socks to help thwart blisters from forming on your feet. The color of your socks is irrelevant, but make sure you have at least twice as many pairs as you have days in the rainforest.
  
  

Trousers

• Cotton trousers are your best choice for a trip through the tropical rainforest. Denim jeans are not a good choice as they dry much slower than cotton and can become very heavy and restrictive when they get wet. Denim jeans are also more likely to cause rashes and blisters when they rub upon your skin. Heavy duty cotton khaki trousers designed for fieldwork are the most comfortable and durable option. Your trousers should also have multiple pockets so you can store important tools for your journey such as a compass or knife.
  
  

Swimming Suit

• A swimming suit is an optional but handy item of clothing to bring if you don't want to bathe in the buff or don't want to get your hiking clothes wet when you decide go for a swim. Make sure the swimming suit is lightweight and made of light material so that it does not take up too much room in your backpack when you're not using it.
