A good fit
I usually go with a size medium but I have been playing it safe with For Days as some of the items seem to run small, and the large was a perfect fit. The shirt isn't form fitting but it isn't excessively baggy either. I have been very comfortable in it and with it.
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
