Various studies have shown that lot of soldiers get injured due to negligence in proper donning. To eliminate this damaging effect, MKU has introduced a special 4 point chinstrap system with a unique double sided lock in MKH/ACH-3 which provides for better stability and at the same time makes wearing this helmet easier.

The new chinstrap retention system and the pad suspension system in MKH/ ACH-4 provides unsurpassed balance, stability, and comfort. The pad suspension system provides impact protection throughout all operational scenarios, including static-line airborne operations.

The self configurable special suspension system in MKH/ACH-4 allows for 2 configurations. The 7 pad configuration is well suited for airborne & cold climate operations, whereas the 5 pad configuration is ideal for high temperature zones. These configurations can be easily carried out by the soldiers themselves.
