I'm trying to come up with a wardrobe for desert hiking. I've got the standard longsleeve shirt and pants, but I was wondering about going a different route - what about a wicking T and shorts, under what is for all intents and purposes, a thin cotton bathrobe? My thinking is it keeps the sun off you but it breathes/moves in the wind, so that you can still stay cool while basically wearing your umbrella. Anyone outside of the Middle East tried this?
