F irst of all, remember that it really does rain in the rain forest. And you'll be doing your laundry in river water, which ranges from clear and red, to thick and muddy. W hite shirts and sneakers turn mud colored in the first hour. You might as well start with tan and khaki colors and worry about ring around the collar when you get home. A rmy Navy surplus stores or Banana Republic outlets are a good place to start, but don't forget K-Mart and Thrift shops.
Many travelers plan on leaving most of their clothing for the natives anyway.
D on't take jeans. They take three days to dry, assuming you can find an open spot in the jungle to hang them for the two or three mid-day hours that are sunny. D o take lightweight, dirt colored slacks and shorts. Khaki walking shorts with lots of pockets are the choice of many travelers. E ven better for coolness and insect control are ultra-lightweight long pants in nylon, washable silk, or Indian cotton.
