The Ronin helmet is made of kevlar. It features 7mm additional cheek panels which are held in place by neodymium magnets. The use of magnets allows to quickly detach one of the cheek plates if you opt to have a better cheek weld on the firearm. There is also an NVG mount on the forehead portion as well as Picatinny rails on the sides for attaching accessories such as flashlights. It also has replaceable lenses. There is a built-in system that prevents fogging of the lenses and an optional ventilation system attachment for the head. To have a better idea concerning these features watch the following videos.
It is also possible to customize the appearance of your helmet by choosing from various colors and camouflage patterns. There is even a US Flag option.

I wonder if the appearance of the gear has an additional psychological effect on the enemy?
