High quality, super soft, good neck height, nice price, ready to go right out of the dryer, medium thick material, works well under a sport coat or sweat shirt, snug fit--runs about one size small. Length is about four inches too long. So, ideally made for tall and skinny people (I am short and thick), but going one size up works fine for me except have to tuck it in due to the length.

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.
