Hello There, The quality is 1 A and the substance is not too thick not too thin. Only I have (visible in the picture) did not understand the meaning of the hole in the T-Shirt as it is actually geeinet for the grommet, but not with the bag on his arm which is intended for an MP3 player. In addition, if you walk at night reflects the zipper. This shirt is also breathable. I've actually bought this running shirt for trail running, but it has become my favorite sport shirt. Hope I could help, if so then evaluated my Rezesion easy :) LG Marie
