Classic snorkel jacket in a larger size - labelled 'L' but the armpit-to-armpit measurement is 73 cm / 28¾ in so it is really an XL or 2XL.  In fantastic condition, with only a few very slight signs of wear or dirt, this coat seems to be almost unworn.  In my view it is an authentic reproduction rather than a vintage original, as some of the production details seem to be too modern.

The outer material, in classic blue, catches the light and has a green tint to it occasionally - very attractive.  It is a very coarse weave nylon, so makes the classic rustling noise if you move your arms when you walk.  This is guaranteed to bring back schoolboy memories - just remember not to cross the road with your hood up!
