This is one of those things that I got super lucky on, and am able to offer these VERY rare helmets to you. These are New Old Stock Gen 2 helmets that have been in storage since the 90s, and are now ready for your collection.
The MARTE, or Mars helmet was one of the first composite helmets adopted and used by a military force, and led to inspire other models like the Schuberth B826, which, coincidentally, was made early on my the same company in Spain that made these MARTE helmets. Anyway, these are EXTREMELY hard to get, but I have a source for a VERY limited number of these.
Once this source has dried up, I will NOT be able to get these again, so now is the time. Military surplus composite helmets are getting increasingly harder to find, especially ones that are this rare, so don't wait until they're gone.
Dates will vary, and although these are new old stock condition, storage wear is a real thing, so these might not be in "perfect" condition, but I assure you that your helmet will be complete and functional. Size will fit a 56-58 CM melon (59 will work too, it'll just fit a little more snug). These are being sold solely as a costume/collector's piece, and are not intended for any ballistic protection, even though the Spanish military has been using these for decades......
NOTE: THESE ARE ON A PRE-ORDER BASIS. PLEASE ALLOW 6-8 WEEKS FOR DELIVERY. YES, THEY ARE WORTH THE WAIT.
