The Smiter, I believe such a LW IS exists and dates back to the 80s. The bunny suit was replaced with a one-piece wooly pully and the whole worn under a flight suit.
This had the advantage of not having to load and unload the flight suit pockets for goon suit/non-goon suit sorties.
The suit was not as tough as the Mk 10 and I don't believe the thermal properties of the knitted suit were as good as the pile. It would also have been interesting try to have a c
p in one, but then again it was nigh impossible having one, or anything else when wearing a Mk 10.
I remember one trip to Kef, I was 'just' wearing long johns and vest, cause bunny suit was too itchy. The bunny suit, a flying suit, and the Mk 10. And a life jacket.
Serving tea was difficult as I had to clamour over all the sprawlling ground crew, use one hand to lift a leg over the spars whilst balancing the tray of tea in the other.
