My husband loves these shirts
Color: Dark Blue, Size: Large
My husband just loves these shirts. He has one in every color, I think. Great quality, good price, breathable, true to color, and super comfy. Nice enough to wear to a nice dinner but can be dressed down w a pair of shorts and flip flops. By far the best find I have found!

Shrink-wrapped shirt???
Color: Clear Blue, Size: X-Large
This shirt arrived in a vacuum packed clear package which caused wrinkles in the synthetic material. Instructions to remove the wrinkles are to run the shirt through a wash cycle. Well, that didn't work! I'm hoping a dry cleaning service can steam press the wrinkles out. Aside from that issue it is a very nice shirt. Sizing good. Fabric thickness and material are very good. Because it is made from polyester and spandex shrinkage will not be an issue.

Great size and cut for an athletic build.
Color: Dark Blue, Size: Medium
I have purchased about a dozen different Coofandy long-sleeve and short-sleeve shirts and I absolutely love them. I'm 5'6" and 175 lbs with an athletic build and I wear a medium from this company. For an average build, they may seem a little "undersized", but if your looking for a shirt that really shows your physique these are perfect. I'm normally a Vuori guy for my athletic cut clothing, but these shirt are one quarter the price, a really nice cut, comfortable, and decent quality. They are cheap enough that I added a host of different colors to my wardrobe.
