Good looking shirt that runs a bit big in sizing.
Size: X-Large, Color: Green Gray
Nice looking shirt for dress up or casual wearing. Feels like silk, pretty wrinkle free. Lots of colors to chose from at a good price. Runs a bit big in size. I found the sleeves very long for me. But I like the casual look, feel and coolness in the heat of summer for a long sleeve shirt.

Great feel, good shirt
Size: Medium, Color: Black
I bought this to replace my excite Express 1MX button up black shirt for work uniform which kept fading with the seams turning a dull gray. The PJ shirt is wrinkle free after first wash, stays black, and is a bit more stretchy. Also it’s way more affordable at $26 vs Express 1MX at $60 ish.
