Great value, good fit, solid material.
Color: Black, Size: Medium
This is a great shirt. The quality is nice given its price point, making it a solid value. It’s breathable, doesn’t feel overly thick but isn’t paper thin. The material doesn’t feel cheap or look cheap, for that matter. It’s incredibly comfortable, doesn’t shrink and doesn’t fade. I love the way it fits, and overall I enjoyed it so much I ordered one of nearly every color.
