Great purchase

Purchased several shirts, all were great quality. You never know what you’ll get when you purchase sight unseen, these are worth it. Great value, style, and comfort. Color is exactly what you see online. True to size.

For work or casual wear, this polo is a great choice.
Material Type: Recycled Polyester, Color: Port Stripe, Size: X-Large
I really like this polo. I've been wearing it once a week or every other week since November. Its very comfortable and breathable. This polo feels like it should last a while. The fit is good. I typcally wear XL and this XL fits great. I've pruchased it in both burgundy and black so far. I definitely recommend this shirt. For work or casual wear, this will look good.
