I love this shirt for camping and fishing.  It stays cool in the hot Arizona summer, but it keeps just enough breeze off in the cool evenings to not need a jacket.  It's easy to wash it in some clean water, wring it out, and keep on going.  It dries fast when wet and has a great evaporative cooling effect in the summertime.  Range of motion is great, and I like the straps inside of the sleeve that hold the rolled-up sleeve in place with a button.  I ended up picking one up for my son as well.
