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.

Great Shirt, but a bit Heavy
Size: Large, Color: Black
Very comfortable shirt and good quality. My only gripe is that the material is a bit heavier than I'd like.
