The ArmorSource LWACH (Light Weight Advanced Combat Helmet) is a solid head protection solution. The LWACH is the newest military helmet designed for the U.S. Dept. of Defense, developed specifically to replace the older ACH styles used by the U.S. Army and other U.S. military forces.

  • provides high protection against a wide spectrum of small fragments as well as handgun bullets;
  • undergoes more extensive testing methods in order to improve the safety of the war fighter;
  • is lighter than the ACH;
  • is a shape used and accepted by the U.S. Government and other military organizations worldwide; and
