Great vest
Color: Dark Grey, Size: X-Large
This lil vest is awesome. A little thicker than I expected but perfect for my cool office. Looks like it cost twice as much. I had my company info put on it and looks like it cost 150.

Vest is heavy and frankly very warm can’t see in what environment I’d wear it because at 40-50 I would use light down coat with sleeves I returned from t same day I reviewed it
