True to size per the size chart. The fabric is soft but it it feels cheap to me. It attracts lint but you can brush it off easily so its not the cheapest material I've dealt with. Also, it is opaque (not see through). There is no front/ back indicator either which is indicative of a cheap shirt in my opinion. Would be friendly for tag sensitive people (to stay positive).

Fuzzballs get wearing once

Color: Black, Size: X-Large

Very smart to wear, but the quality is terrible so after one wash the collar start fraying and fuzzballs start forming. Very disappointing.

Cool shirt

Size: X-Large, Color: Black

Very comfortable and light weight. The material is like a moisture wicking material and feels cool on my skin. The shirt stretches and moves with you and is nonbinding in the areas of your arms and neck.
