This item does not include the airline or hose attachment. >>>This HERO helmet set has the headset with communication and amplification ability, as well as flexible boom microphone (not tested) that is for actors for close-up shots (see screencaps). These are much more rare to find, don't let this item pass you by! The helmet appears to be a version of a flight deck crew helmet.
I believe the cloth portion of the helmet may have some subtle additional coloration to it to give it the appearance of age. There is also some real dust and dirt on there, presumably from the many weeks of shooting out at Eagle Mountain, where the final battle was filmed. The style of ear protection varied amongst the costumes, so this small detail may or may not match the "hero" version you see the main stars wearing, but rest assured they are all from the same lot. The Mask is model CM-6F1, manufactured by Mira Safety. They sell a version of this mask for retail customers.You should expect to see some surface scratches on this item, there was a lot of stunt work done out at the filming site. Be the hit of your next halloween party, comic-con, paintball war or temporal pincer, I haven't seen any other sellers with this item!
