“More for casual wear than exercise”

“This is an attractive top with good length and body coverage. It ends there. I noticed when putting it on that the arm holes seemed slightly loose or oversized, but thought it would be ok. During a 5mi treadmill run, a short time into the run, I could feel the trim on the armholes chafing under my arm. One of my underarms were chafed so badly that it bled some onto the shirt. This shirt is not suited for running or any activity where you will be briskly moving your arms if you find it fits you similarly. Unfortunately, I cannot return it now or I would. It is also a heavier fit shirt, so wouldn't be good for warm-weather exercise--it's definitely not lightweight--more like a double layer shirt--which is what also contributed to the chafing, the material is very dense. It doesn't move with you well. Would probably be ok for cycling or casual wear, this would not be one of my go to shirts for exercise.”
