Little bit on the small side
Size: XX-Large, Color: Black, Pocket Description: Plain Front
Run a little small, but the quality of the shirt seems to be pretty good. It is thick and nice. Warm and softness are both good.

Impressed for the most part
Size: X-Large, Color: White, Pocket Description: Plain Front
Going to give it 5-stars for now, well see how well they hold up after a few washes.
They for sure feel like nice heavy-weight shirts.
I like them alot for that reason.
They have a boxy-fit though, so not "fitted" at all but thats fine for me because I am using them as under-shirts.

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
