Obviously, it's a motorcycle helmet, but it has a few things that other helmets don't have.
It offers ballistic protection (MIL STD 662 standard) using a 17 grain fragmentation simulator at a velocity of 1600 feet per second. That means when those SUV drivers start firing their hand guns at you, at least your head is safe. You can also use the helmet for parachuting, as long as you do not exceed 150 G average at 10 feet per second (damn, .. there goes the planned weekend HALO jumping).
The MMH II can be purchased with protective visors or goggles, your choice (bother are bullet proof, so those pesky bugs should not be a problem).
It can also be fitted with their communications cords and adapters, so you can communicate with the tanks and other armored vehicles (or other motorcycles).
You'll need to supply the communications gear though; the cords and adapters can be purchased from Gentex.
What's going to make this helmet uber-cool, is that you can connect up the MBU-12/P Oxygen mask. Great when riding in a smog filled city. Or for night time riding, you can connect Night Vision goggles (Night Vision goggles are an optional extra).
Now... isn't this the bees knees???
Price: Don't know, but it's not going to be cheap...
