I think if they made them out of more modern material it would be ok. I have acquired a green one (new-ish issue Jumper, HW, OG, for the annoying of WOs of) and it’s much less itchy than our old blue / grey. And the v neck looks daft without a tie IMO.
As much as a pain it would be to get into, I’d l love to see the original “full” dress returned, with a high collar tunic and leather pilots cap as head dress.
I have one of the approved blue leather jackets. Nice and warm even without the winter liner and I don’t have any wings. As YO8102 mentioned, SNCOs of any branch (including RAFAC) can wear one but at personal expense. They currently sit at ~£500 but will probably last forever if you look after it.
When I was RAFAC I asked Aviation Leather Craft for some leather off-cuts so I could have RAFAC embroidered onto the bottom of the slide then sent the pieces off to Combat Logos for the braid and lettering to be added. TBH Alan did a fantastic job and I’ve still got them in a draw. I’m back to VRT now so I just have my pins on normal rank slides.
