I've had one of these shirts for several years. I have no idea where I got it, or when, but I really liked it because it was so light and wrinkle free. Eventually, I decided to see whether I could figure out what it was and find more of them. That turned out to be easy, and now I have several. During the heat of summer, it's like wearing nothing, while still being protected from direct sun, while not needing a whole lot of maintenance to keep looking nice.
