I wore the Vietnam era M-1 helmet from 1975 to 1985 and then an original K-Pot from then until 1993, and an occasional SPH-15. I seem to remember the K-Pot as being heavier than the M-1. In Desert Storm, 1st Cav made such an issue of keeping your helmet on that they earned the nickname of 1st Kevlar Division. The ironic thing is that our Vulcan TCs had their heads up above the vehicle armor, wearing a CVC helmet, which was just a plastic bump cap.

There’s at least one company that will take an older style helmet and reconfigure it to a more modern build.

But to the point of the article, there seems to be other more economical ways to get a modern helmet.
