I used Propper Gear about 15-20 years ago and it was of excellent quality. This shirt is not like that at all. It's so hard you can hit a tramp with it, and the material rubs my hyperacusis harder than modern music.
Pros
not quite the material I expected. I thought it would be softer. it's a bit hard
Cons
The shirt may require ironing or special care to maintain its appearance.
