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.

Weirdly thick material, I wasn’t a fan but it’s a good sleep shirt

Just what I wanted.
Color: Black, Navy Blue, Wine Red, Size: 5X-Large
These may have just become my standard shirt to wear. Feels good whether tucked or out. Drapes well and fits well. So far, I can see it adjust to the different undershirt I may wear. Will probably order another set in other colors and a back up set of the basics because they will get worn a lot.

Its alright
Color: Black, Size: 5X-Large
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).
