Years ago I bought my wife a Stearn made model IFS-584 insulated flight cover-all. ( Fire resistant Anti Exposure flight suit.)
It is a size 42 short and she wore it maybe 10 times over the years.
It is in great shape. BUT she does not like flying anymore and has been into the cookie jar a few too many times.
So what does the peanut gallery think it is worth. I can't find anything on my internet connection except a Coast Guard test where they made some poor volunteers sit in cold water to test the thing.
I will post a couple pics if I can get my camera working.
