This shirt is extremely comfortable and very light weight.  Perfect for the Southern California climate.  I liked it so much I ordered 2 more.  One thing to note is that the color of this particular shirt did not show up correctly on my computer.  I was expecting a shirt that was more blue than what arrived.  The shirt is actually a light purple.  I still like the color, but if you are expecting blue and do not like purple, you will not like what you receive.
