Very cheaply made
Size: X-Large, Color: 02khaki
Not happy at all … this shirt did not arrive as displayed. It’s pictured as two tone giving the impression that it’s a dark brown fabric on top and a different light brown fabric at the bottom… it’s a thin one piece shirt with what appears to be a spray paint top. Very cheap looking

Good quality shirt!
Color: Black(pattern1), Size: X-Large
My husband got this shirt to go along with his new belt buckle he got and I have to admit, I was skeptical on how it would look on him (he’s normally just a t shirt and basketball shorts kind of guy) but I love the look! I’m trying to convince him to wear it more often! The color and fabric quality are great! It’s soft and he says comfortable! The size was true to him! He wore it at work and said it lights weight and breathable! He wouldn’t let me take a picture though…
