The back side of the shirt has a looser weave compared to the front, which scared me when I saw it, but believe me, it is not unattractive, nor does it show, on the contrary, it is what you need when you are running. It is a high-quality shirt with a nice fit, the fabric is soft without causing any issues in the chest area while running. In terms of size, I followed the chart and it fit me perfectly. Also, the sleeve length is short to regular, I generally don't like sleeves that reach low. A very good choice. I hope I helped you.

Very good application ideally made for exercise with the back part constructed in a way that allows the body to breathe very well.
