I was very excited about making this purchase; Columbia is one of my favorite brands, especially for their sweat-wicking apparel. Because I ain't got time for sweatin'!

Anyway, I'm 5'6, 130-135, and the medium fits great. With khaki or jean shorts and some classy sandals (I suggest Clark's Artisan, personally) and you're set to go! The only reason I'm giving this 4 stars is because I had to send mine back for an exchange. The original shirt I received had this odd stripe on the left shoulder where it appeared that the material had been rubbed to a point that it was shiny and almost see-through. But otherwise, I still love Columbia and their products. I've already been shipped a new one.

I would recommend this shirt, especially if you're going to be outside for a long time. This shirt will keep you cool!
