Great fit.
Fit Type: Regular Fit, Color: Charcoal Heather/Charcoal Heather, Size: 5X-Large Big
Im 6'4 360lbs. They're not thick but and the neck is a little looser than what im use to. But overall im happy with the quality and the length of the shirt. I got a big belly and the shirt doesn't expose any of my belly and not too long where. It looks like a tall tee. Definitely will grab these again.

I ordered the two pack black tee-shirts.

Better than the equivalent from two other major brands.

Soft
Fit Type: Regular Fit, Color: Navy/Dark Blue, Size: X-Large
They feel nice, but shrunk a little in the wash. The fit before shrinking was perfect, afterwards it was just slightly too tight. The length before and after was too short for my preference. I do have a slightly longer torso though. If you are normal height then they will likely work great for you.
The material is super soft and comfortable.

So soft and attractive
Fit Type: Regular Fit, Color: Heather Grey/Heather Grey, Size: X-Large
Bought these for my husband. He loves the fit and they're so soft and don't wrinkle easily. They're also a nice weight. I've washed them a few times and they don't pill or shrink. Wish they came in a larger variety of colors, but plan on ordering more.
