As I don't drive so rely on buses but prefer to walk if I can (and having to exercise the Springer Spaniel frequently) I have been trying different jackets with surprising results. I have walked out in my 1943-dated RN Duffel Coat: warm but too bulky, weighs a ton! USN A-2 Deck Jacket: love the warmth, ease of movement, inner cuffs but too short. RAF MK3 cold weather jacket: pretty similar to the USN jacket but again too short (cold bum!) Kriegsmarine Parka with lining: very warm but like the Duffel, too bulky, hood is useful though. Finally, a stalwart of British workers, 100% wool Donkey jacket, ex-parks Department (gravedigger!) recently bought in charity shop for £5.00: superb, very warm, comfortable, deep pockets. For non-UK residents, a Donkey jacket is like a Pea Coat but single-breasted. So I have chosen the non-military option and am pleased with the result, I satisfy myself that I can look like Joe Strummer or Ian Dury who at times both wore these jackets! I didn't dare wear my original Irvin so that didn't count.
