Good Choice
Size: X-Large, Color: Light Blue
Good fit. Comfortable. Looks great. I bought one color, then ordered 2 more. I am 5'9" and weigh 200 and I bought size XL. Perfect.

Yaaaasssss baby! YASSSSSSSSS!
Size: Large, Color: Navy Blue
I get hot and sweaty all the time- I could be sunning in a thong in below zero and still be- I need a fan. This shirt is NOT HOT- its handsome, feels nice, my wife loves it, it looks good dressed up or with shorts and I'm not needing to mop my face. It breathes and looks good. The fit is nice, I went up a size because it seems to run a wee bit small, thankfully the larger size is not longer so it doens't have to be hemmed or look silly.
So pleased. Wish there were other designs that weren't so crazy/flashy because I would order more.

La recomiendo.
Size: Small, Color: Black
Solo no me gusto la doble cobertura de los botones, ya que se hace un poco difícil ponertela.
