Boyfriend loves it for golf ⛳️! Super comfy, cooling, soft material
Size: X-Large, Color: Grey Stripe
Boyfriend wanted me to leave a review to let all the people that may want to buy this.. that they need to right away! I am a witness to how soft, smooth, slick, and sexy this shirt is! Looks good on him, and feels good too! It is some seriously great material a shirt, versatile, and very nice fit. He is 180 lbs 6’2 and uses it when he goes golfing. He had me order it in a few other colors as well! Washing it has been a breeze for us as well.

Great Shirt for the $$$
Size: XX-Large, Color: Green
I wasn't expecting much for the price, but I liked the look and the color so I ordered it. After receiving it I can tell you with confidence this is a high quality polo and the feel is amazing. Very comfortable to wear all day, wicks moisture very well, and looks like an expensive shirt you'd expect to pay 3x as much for. Very please with this shirt.

Although it was a quality made shirt, not happy with the fit and style.
Size: X-Large, Color: Grey Stripe
Order this in an XL size for my son-in-law for Xmas. He isn't overally big, but likes the XL size for a little more roominess. After Xmas he tried it on. Although it was a quality made shirt, he wasn't happy with the fit and style. A no hassle return.
