Primo!!!
Size: XX-Large, Color: Black
The fit was right, the style was sexy and I exuded that same mentality while wearing it! I'm 230lbs 6'2" and I have the 2XL. This top is perfect for cooler weather not too heavy not too light it appears to be just right. I love the quality.

Good looking shirt
Size: X-Large, Color: Brown
I like it. Nice material, it's warm, and it looks good. The shoulders are a little broad but that's what I get for having narrow shoulders.

Someone's trash is someone's treasure.
Size: XX-Large, Color: Mottle Grey
Have you ever thought to yourself, "This t-shirt needs long sleeves, a zipper, and a collar?"
Me neither, but someone did and here we are.
If that is your fit, you have found your treasure.
