Loving this soft smooth Polo!
Color: White Black, Size: Large
Fits like a glove. Loving the material; smooth soft feel of the shirt. Quality Feels very similar to $75+ golf polos. Washes up perfectly, no wrinkles. Collar contrast in color is a nice touch-Highly recommended!

Color: Light Blue, Size: X-Large
DEMEANOR men’s golf polo shirts offer a winning combination of comfort, style, and performance. The fabric feels light, breathable, and moisture-wicking — perfect for sunny rounds on the course or casual weekend wear. The fit is tailored without being restrictive, and the variety of colors makes them easy to mix and match with golf pants or shorts. Durable stitching and quality materials mean these polos are built to last. A great addition to any golfer’s wardrobe!

Silky smooth fabric
This is a cool and comfortable polo shirt. It's made primarily of polyester with spandex as well to give it added stretch. It fits as expected in my regular size. The color and pattern appear like they did online. It falls somewhere in between casual and dressy and should be suitable for most settings. The fabric is smooth with a bit of sheen and feels cool to the touch. I've machine washed and dried it several times and it still looks great. I love that it doesn't wrinkle and I never need to iron it. Everything seems well put together and I think the quality is great.
