This shirt is a cheat code
Color: Black, White, Navy Blue, Light Gray, Size: XX-Large
These shirt fits my body so perfectly! I’m 6’5” 310 pounds but I look 260 pounds. I sweat easily and I’m very sensitive to the material a piece of clothing is made of. This shirt is lightweight, extremely breathable, and feels like silk on the skin. It compliments and accentuates my contours to enhance my physique. I only tried on one and I’ve already ordered 12 more hehe. This is a cheat code.

I Love the collar
Color: Black, White, Navy Blue, Wine Red, Size: Large
Great T-shirt. I can wear this casually with jeans or with a sports coat. The fabric is soft. There is no label in the collar, so you can wear it however you want.

NOT a compression shirt
Color: Black, White, Navy Blue, Wine Red, Size: Large
These are well made with good quality material but are not what I was expecting given the picture. I am an XL and ordered a L because I wanted them to be tight (which they are not.) I decided not to return them because they are good shirts with a reasonable fit, but be advised these are not compression shirts.
