GMax GM54S Derk Modular Helmet 

The modular design allows the "flip-jaw" to rotate further back on the crown of the helmet. The further rotation of the flip-jaw not only increases the user's line-of-sight when in the raised position, but it also lessens the user's fatigue by maintaining an even distribution of weight across the helmet.
