I bought two sizes to decide between, but will be returning both. I love the idea of vented sides and underarms.....I really wish some of my other outdoorsy shirts had that. Love the zippered pocket at the seam; the teal color is gorgeous and screams tropical island. And the extra tab of fabric on the collar to pop up and make it truly stand up to block the sun!! However, this shirt is so boxy!! It is a tad too long to wear untucked  it looks frumpy and unkept. And forget trying to tuck it in....it billows everywhere and makes me look twenty pounds heavier, plus  negates the zippered side pocket. Also I do not like that the chest pockets close with Velcro.....this cheapens the look and, in my experience, does not launder well in the long term.
