UK Military tailoring can be a bit varied!
When I joined the Royal Air Force, I was issued with a raincoat made of rather cheap material like everyone else's. But after a year or so I hung it on the mess coat pegs (no coats in the mess hall!) and when I came out from dinner it had been stolen.
I went to the stores to get a new one and was not yet entitled to a replacement but they said I could pay for one. It was far superior to everyone else's! Nice material, probably from a bygone age as this was not the pile em high and push em through bootcamp the original coat came from.
