Okay shirts if they fit. Neck stretches out some with washing.
Decent shirts. It's difficult to buy clothes online because you don't know how they'll fit until they arrive. The small was too small, and the medium is just a little loose. I'm 5'8" and 150 pounds after losing 65 pounds in a year. I work out and have some muscle. Shirts look good on my chest, but the sleeves are a little too long, and the neck is starting to go bacon after just two washings.

Not worth the price.
Color: 2 Pack(black+white), Size: XX-Large
At best these T-Shirt should be in a 4 pack at maybe $10. Quality is not good, they are very thin, very stretchy and the collar does not hold its shape. Would not buy again.
