This flat black helmet is a nvg night vision (or thermal goggle device) top metal bridge mount base with one single clear step inn visor and outer boom mike as well with Gentex MBU mask bayonet recivers. I haven't seen these before.
Helmet comes like shown (less black mbu23 oxygen o2 mask)!! This is one of only 2 helmets I have online in 2sizes. Ask prior to biding if your size is still availeble - ONE helmet in already flown mint condition comes with - ONE original military black XL transport bag and - ONE comms / harness set less!
Mask I cannot say if it's a army aviation helo rotor wing helicopter helmet or fixed wing jet supersonic aircraft helmet. Looks to me as new generation helmet series to new age ultra light carbon helmets commng up. Boom mike and mask reciver's looks to me it was tested for both aircaft types. Note this is one of 2 existing flying helmets.Both in 2 different sizes. Ask prior to biding if your desired size is left for you it was made for nato or usaf us air force, navy usmc uscg ops seal delta force or any close to these.
