Nice Qualtiy for the Money
Size: Large, Color: Light Blue
I originally ordered this vest in XL based on other reviewers' suggestions to up size, but I returned it for a large. Vests should fit snugly and not be loose. I'm 5"9" and 175lbs and the large was a good fit for me. The material is not as heavy as I expected based on the photos but it is not flimsy. It is well constructed with a nice liner. For the money it is a really nice item. I have nicer vests but then they cost several times what this one did. Overall, I am very happy with it.

Not terrible for the price. Not super high quality.
Size: 4X-Large, Color: Black
Not bad for the price. Fits a size smaller. I can wear it standing up, but need to unbutton it to sit down. I have very little faith in the buttons. The sewing looks rushed. I may cut them off and replace them. Brown buttons with a black vest? Odd choice. Not sure what the half moon pocket is for next to the button holes.
