Machine Washable but NOT Machine Dryable!
Seems well made and fits me well (6'2", 196 lb). I like the feel and color. However, contrary to lots of the reviews saying the shirt the received, mine was 100% Polyester. The instructions say machine washable. But upon receiving the item, its label says "do not tumble dry." I intended it for a two week+ cruise where washing it and quick drying will be essential. Drip drying would be very inconvenient.

Thicker shirt, not jacket or shacket.
Color: Olive Green, Size: Small
It's not a jacket or a shacket-- too thin for that. But it is a thicker shirt, very soft, and could be worn as business/dress or casual. We didn't keep it, because it wasn't what we were looking for, but it's a nice shirt. Bigger than we were hoping for a 10-year-old boy (who is very tall for his age).

Consistency
Color: Black, Size: Large
Honestly, I was expecting better quality, but I guess it is reasonable for the price. One thing I noticed is that the brand does not seem to have consistency in the materials they use. I was expecting to receive the same quality and feel that I got with the first shirt I purchased, but unfortunately, that was not the case with this black shirt.
