All our helmet models
featured include the Advanced Combat Helmet
(ACH) Blunt Trauma Protection Pad System - 0.5" - 0.75" -
1.0" thick pads of engineered impact protection to cushion your
skull from impact.
Many other helmets
look the same on the outside, but have the older generation nylon /
leather / open cell foam interior suspension - NOT up to modern standards.
If it says "universal fit", "comfort fit" or "standard
fit", or anything other than ACH blunt trauma protection pads,
you are missing critical protection for your brain.
These older systems
can be fine on comfort, but offer MUCH less blunt trauma protection
on impact. If your helmet is of this type, we strongly recommend that
at the very least you upgrade your helmet with a Foam
Impact Liner to bring blunt trauma protection closer to the latest
mil-spec. Really the best solution is to retrofit the ACH
blunt trauma pad system.
