Surprisingly awesome. Seriously. And I hate buying clothes.
Size: X-Large, Color: Black
I'm 6'1", 215 with large shoulders and chest. "Athletic dad-bod." Nothing fits me perfectly. I'm constantly stuck between an XL and XXL shirt, and a 37x31 pant---so literally nothing fits me and if you're a big guy, we all know that most polo shirts look like crap and fit like garbage bags.
The shiny tone first made me skeptical. I wasn't even going to take it out of the package. But for $19, I said screw it.
It fits really well. Not slim fit, but not "Ralph Lauren trash bag regular fit." It's soft like textured silk. It looks good and is the perfect length if you're 6'-6'3.
And no--I know your first thought with the texture and shine is "does it look like a cheesy club shirt on a NJ Italian guy?" Shockingly, no...it's actually really nice (yeah--I had the same thought).
It's stretchy. It's relatively form fitting, and it's cool to the touch.
I immediately bought 3 more.
For $19--just buy it. You won't regret it.

Good shirt
Size: Medium, Color: Teal 02
Love the color and the design of the shirt. The small threads it’s made out of starting to come loose though. Now when look down at chest and stomach area, there are 15+ little strings that pop out of the shirt.

Awesome shirt!
Size: Medium, Color: Blue, Size: Medium, Color: Blue
This is a nice shirt! Let me start by saying I am 6 foot 2, 195pounds with about a 40 inch chest, 42 inches on a good day! Ha ha. I ordered a medium because I wanted an athletic fit. The medium fits just right. For those wanting a normal, roomier fit I would recommend the large for my size. I’ll get a lot of compliments when I wear this shirt. What I like about it is that it is wrinkle free and looks great, I would not wear it on a super hot day with a snug fit. I do live in Florida, so that makes a difference. I also ordered the black one, both the blue and the black look very good for dress /casual. It’s polyester so it’s not super soft, which is OK. That also means it does not shrink.

Nice shirt but seems to be confusion over the color/pattern.
Size: Medium, Color: Teal 02
Nice shirt. Looks sharp and feels comfy. Lightweight and breathable. Definitely an "upscale" polo that looks like it costs more than it does - so very happy with the value. Fits as expected for the size. The only issue is that I ordered a color and style called Teal-02 and they sent me Navy-01. The color and pattern is different. It's not bad, just not what I ordered. I requested a resend of the Teal...and got the same Navy color again. Annoying.
