At this point I'll mention the Musto Ventile Arctic parka.
This style of Musto coat was made in three grades, of which the Ventile version was the most expensive. I only know about it because I picked up the least-expensive version in Goretex at their York outlet during the Black Friday sale in 2015. My version had begun life in the £700+ range and had been reduced to half price. When I decided - after a lot of agonising that I could thoyle that much hard-earned - I was pleasantly surprised to learn that the sign "Up to a furthe 20% off selected items" included this coat so it "only" set me back something a shade under £270 (which is why I used the expression "least-expensive."
The Ventile version has remained at full price. It's some sort of a limited edition but not moving fast.
FWIW, when I bought mine there was a chap trying on one of the middle-priced ones, pretty much like mine but with the gold level of Primaloft. On the fashion point, it was bright red and covered in reflective Musto ads. That chap's wife was encouraging him to splash out "You'll kick yourself later if you don't buy it" and she explained to me that he was a keen sailor. Must logos all over your coat probably carry more kudos in those circles than mine. The harshest conditions mine has protected me from were watching my grandson playing soccer in Queensbury. Worth every penny.
And, unlike the Ventile version it's washable.
