First off, you need to know what a Mitznefet is. The Mitznefet is a mesh helmet shaper used by Israeli troops to break up the outline of their helmets. See below for a photo.
Agilite just introduced a MultiCam variant of this bit effective bit of Israeli kit. Since it’s made from mesh, Agilite also suggests that it can be worn without a helmet, directly on the head, allowing “for an air flow to the head and for heat to escape keeping you shaded, camouflaged and cool in combat environments.”
