I like it, it's smooth and lightweight.  XL most likely means XL, and usually all my hiking shirts are XL.
But when you are layering, that last shirt has to be big to fit over all the other shirts.  Since I bought this shirt for an upcoming hiking trip  in the desert,  where layering won't be such a big concern, I will be buying another of these in the large size,  at 28 dollars they are half the price of all the other Columbia shirts.
