Great find for less
Color: Wine Red, Size: X-Large
I purchased two of these in different colors for my husband. They were way cheaper than other options available. I was nervous about the quality with how much cheaper, but he loves them. And I must say they look very good on him. Happy with purchase, true to size. My husband is 6'2' and no complaints about the length.
