This shirt is a smooth material that is common for athletic type shirts. It is thin (but not sheer) and breathable, and a good weight for summer workouts. It does wick moisture without leaving those ugly sweat patches on the back and underarms.Fit is relaxed, and the large was true to size. I don't like a fitted shirt for workouts, so this is great.Although the tag says to handwash this shirt, I washed it in the machine without any issues. I did hang dry it due to the spandex content. (92% polyester, 8% spandex)This is a solid choice for a comfortable workout in warm weather.
