I'm currently looking for nylon fishing shirts, shorts and pants with big pockets that dry quickly when wet.
If available in the US then the Craghoppers Nosquito Cargo Shorts or Convertible or double convertible trouser might be worth a look.
Craghoppers Convertible Trousers
Long sleeve and short sleeve shirts are also available. Some even have a Bear Grylls moniker on them.
They are pretty good at keeping away biting insects but not so effective at keeping away the kidney thieves and rabid dogs (which no one has yet seemed to mention).
