Does anyone know if they had this costume on display at Celebration? Good pics from Celebration would go a long way for making out additional details as well as information on the materials used.
Offhand, I think that whatever material was used for the base flightsuit is pretty heavy judging by the way it drapes and I'm think that this would be a hot costume to wear. My guess is that the suit is made from Nomex but that would be unnecessarily costly, a heavy cotton duck might be more likely.
I can almost say with certainty that it was NOT on display. I have been on a lot of Star Wars related site this weekend and seen plenty of photos of Star Wars:TFA props and costumes on display and i have not seen anything Poe or Resistance Pilot displayed.
