As probably the only one here who owns the helmet, flight suit, and Hoth jacket I can hopefully clear somethings up. The collar is pretty stiff can alter the angle of the helmet when wearing it. With limited mobility being strapped in also means movement in the chair is limited and a helmet visor bumping into things can happen easily. I've sat down in all my gear and all kinds of things shift out of place just by doing that motion alone. Again... I only can confirm this cos I own these items. ^^

Nice vacum cleaner tube on that suit. :D It's really impressive. :)
