The perfect golf shirt for those looking for a more slim fitting, less baggy, functional, and fashionable shirt compared to other brands and the "old school" style polo. Under Armour does it again. The innovation and design is why they are a global player and gaining ground on Nike. Super comfortable, flexible material that is also UPF to protect against the sun. Slimmer fitting than a regular golf shirt so shorter sleeves, shorter in length, and less fabric in all places that make shirts baggy and get in the way of your movements on the course. This is a "Loose" fit on the UA scale so it is not the super trim fit "Fitted" but its still more trim than other brands. I am 5'-9" 185lb muscular athletic build that could stand to lose 10lbs or so and the Medium is the perfect fit. Not too tight, not too baggy, perfect length tucked in. Once you go UA you wont find yourself wearing any old school cotton anymore, even if you are not in the FL/GA summer heat down in the Southeast!One thing to be aware of that I found...I have this shirt in multiple colors and most of them are the 2016, new UA shirt. The white I have (White 100) is actually an older version from 2013. Material is less comfy and more like full polyester and appears to not be 30+ UPF which may be the difference. Still a solid shirt but just comparing you can see how much better the 2016 version is with 3 more years of tech added in. Just FYI.
