Great tee
Size: X-Large, Color: Medium Grey Heather
It’s a nice cotton material…not thin, just perfect. After washing, it also kept its shape.

Runs small
Size: XX-Large, Color: Navy
Definitely go a size up. These run a whole size smaller than designated. Material is also heavier than a regular t-shirt. Quality seems okay

Fits well and comfortable!
Size: Large, Color: Eggshell White Black Mariner Stripe, Size: Large, Color: Eggshell White Black Mariner Stripe
This shirt fits my husband very well, it is true to size. It is soft and stretchy enough to be comfortable. I bought this as part of a costume but my husband wears it around the house now because it's so comfy.
