Its just an old high viz. You have to remember that on the west coast its not a fashion issue wearing them. Folk are perfectly happy to wear them out as long as it fills the vital role of being warm/water/wind proof.
You can get a Helly Hansen wind proof Hi-viz jacket for 30 quid.
And a Sioen artic jacket for 70 quid.
If you went for a none high viz same type of jacket which is of similar quality and wx proof you would be double if not three times the price.
