Cool Cuban Shirt
Size: Large, Color: Black Dark Gray
Looks nice and lightweight. I hand washed it and it turned out well. I used an iron to lightly press it. Overall the wrinkles were not bad. Would recommend

I just wish it wasn't vacuum packed.
Size: Large, Color: Black Light Brown
If the shirt wasn't vacuum packed to introduce bad creases/wrinkles, this would be a 5 star review. For the price, this is a nice and comfortable shirt. The thickness is really good for a polyester/spandex blend shirt; it's the right thickness for a summer shirt (because polyester doesn't breath at all). The rather small amount of spandex makes it just stretchy enough to give when moving. It wears a little like a fitted shirt, but it's not too tight at all for a bigger guys. It's not a loose fitting shirt, but it still feels like the correct size (my size was large). Note: This does have a bit of a V-Neck style, there's no button for the neck and the highest button is lower than most shirts. Unless you've a good iron with a steam feature, you're going to have a hard time safely getting rid of the wrinkles/creases from the vacuum packaging. This is a delicate fabric blend and high temperatures will permanently ruin it. I tried to quick wash and low temp dry in a machine with no results. Using a good iron on delicates/synthetics heat setting wasn't quite hot enough to undo the creases. Several steam blasts did wonders, but this was a time consuming process. You might get away using a drying machine at a higher heat for a short burst, but it's a risk. The stitching is good for the panels and arms. The different colors are different pieces of materials and not just dyes. The stitching at the bottom of the shirt, however, is jagged; not terrible, but it's a blemish.

Nice product but size is not as expected
Size: 3X-Large, Color: Green White
This shirt is really nice and really stands out only downside is the size isn't as expected. I usually wear a 2xl and decided to go with a 3xl and it was still a bit too fitted for me liking..Disappointed I couldnt use it
