Leonsniff,
There are a couple of stores in South Africa that sell some pretty handy flying clothes. Cape Union Mart in one that sells light weight trousers that are great for flying in, and then zip off into shorts. They have loads of big pockets on the sides too to keep things in.
They are handy to wear when flying, as you get the benefit of long trousers when flying, then when you arrive at your nice hot destination, just zip off the bottoms and voila a pair of shorts without having to take extra along.
They also sell some nice safari style shirts, which again are great for flying in, as they have lots of pockets and are lightweight and comfortable.
If you pay a visit to Jeffries Bay, there are a few outlet shops from most of the major surfing companies too to stock up on cheap shorts and t-shirts for the time off round the pool or on the beach. There is also a shop chain called Mr. Price that sell cheap clothes too.
Clothes in South Africa are dirt cheap, so pack lightly.
