Medium quality

The general feeling with body is good enough. It is normal to slim fit witch is great for me.
There are inline strips next to neck and shoulder which are a little bit scrating.
The material of sleeves need to be more elastic. When you put the fingers into small holes, each sleeve are stretched.

It is new cloth. I will have safe opinion after many washes.
