This is the shirt you would wear into the desert.  it is very light, quick drying and white.  You can wash this shirt in a sink and hang it to dry and it would be ready to wear in no time.  It fits a little tight and the arms are a little too short.  (XXL on a 6'3" frame).  The white did not work for me because I got it too dirty doing water sports, but if you love walking in the heat, this shirt would be perfect.
