Super comfy and light weight
I really like this shirt. It's soft and comfortable, not super hot but not at all see-through either, despite being a light color. It is a bit long on me, but I'm short so I usually expect that. The small otherwise fits me well (5', 120lbs, athletic build).
Rated 1 on a scale of minus 2 to 2, where minus 2 is Runs Small, 0 is True to Size and 2 is Runs Big
