Runs big. Fabric is nice. Love the color
It's a nice color of green and feels great. I ordered a medium due to the reviews. It's a larger than a normal medium so it's slightly too small. I usually wear XL and sometimes L. So, it does run big. I returned it but probably will order a L.

shirt is thin, sizing is useless
The shirt is thin but okay. The sizing is useless. I purchased a large and a medium. Each is marked with the size (L and M), but the two shirts are exactly the same size. Laid flat together or held up by the shoulders together, these two shirts are EXACTLY the same.
