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).

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.
