I use Dri-Release shirts as work shirts in the south Florida sun.  They lose sweat quickly and can go wet from outdoor to air conditioned indoor without the big chill.  They are also excellent base layers for winter in cold climates.  There are a number of specialty and designer products that perform the same way but cost a lot more.  The brand I used to use is no longer made so I gave these a try.  The tail is a little short for my liking, and even at this price it is inexcusable.  But they function well.
