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.

Nice Fit
Color: Black, White, Light Gray, Size: 3X-Large
I picked this up looking for something simple but clean, and it delivered. The fit is comfortable, the material feels solid, and it looks good without needing much effort. It’s one of those pieces you can throw on and still look put together.

Good value, soft and comfortable
Color: Black, Army Green, Light Gray, Size: 4X-Large, Color: Black, Army Green, Light Gray, Size: 4X-Large
Initial thoughts are very positive with this 3 pack shirt set. The green is similar to an OD military green and the black and gray are standard color shades. Material is soft and sizes are true to size. The mock turtleneck isn’t too tight but may still be a little annoying to some people. I do question the amount of spandex in these shirts. Tag says 5% but these shirts are extremely stretchy and feels like a higher spandex content. It’s also a little tough to figure out which way is the front of the shirt. Visually rhe front does have a lower collar line than the back but would still be nice to have a brand tag printed in the back of the shirt for quicker identification. Overall for roughly $12 a shirt these are a good choice for everyday wear. I will update rating if these shirts fail to meet expectations after further use.
