The MICH (Modular Integrated Communications) helmet is more practical and comfortable and offers better defense from collisions. 
MICH is shallower than PASGT and has the visor removed. It is composed of a four-point chinstrap suspension system attached to the inside of the helmet with a series of Velcro, and a seven-pad system with the pad made of two sorts of foam materials. 
The most crucial feature of MICH is that a duplex communication module can be installed under the earflaps to replace the bulky headset system, thus improving soldiers’ battlefield perception and coordination capabilities. With only medium and large sizes, MICH can be adapted to different head shapes with pads in various sizes, which can configure according to buyer's needs.
