MAD Boom,
I'll pass on your regards to her good self.
As to why the decision has been made, I'd guess that it would be to save a few shekels.
While I agree that the FR CS 95 gear is a bit more comfie in the warmer climates, it's still a pretty poor substitute for something along the lines of a proper 2-piece flying suit with pockets, zips and knee-boards in the usual places. The Spams along with many of our other erstwhile allies see fit to supply their helo crews with such kit but we seem to be pursuing an inferior option.
I think it begs certain questions about FOD, and cockpit organisation and ergonomics that aren't asked when you're wearing the good old-fashioned fire-proof drinking suit. I'm very happy to move on and go for a single solution that works in all situations but I don't believe the FR gear is it......
