500e
I wear Carbon X under my nomex flight suit in the summer and under my goon suit in the winter. Have done for about two years.
It isn't cheap! and it wears thin around the knees and elbows if you fly as often as I do in the SNS.
I reckon it's still worth it though.
I always wondered what happens to the rubber neck and wrist seals on a goon suit, in a fire. Napalm neckless?
