The moment I put this very comfortable shirt on I felt an overwhelming desire to punch things in the face. It was great while I was in the shop, I was super productive. The problem started when I had to go to the big box store for materials. I would not recommend wearing this shirt when you might run into idiots, morons, or lazy people. The urge to punch them in the face will be almost too strong to resist. The material is comfortable and does not restrict the punching motion, it is true to size so you don't expose your gut if whatever you are punching in the face is taller than you, and it breathes well so you don't get sweaty if you run into a large group of idiots who need to be punched. All and all I am very happy with the shirt, highly recommend; just be sure to wear it responsibly if you are going into public.
