All our helmet
models include the Advanced Combat Helmet
(ACH) Blunt Trauma Protection Pad System
or 0.75" or 1.0" thick pads of engineered impact protection
to cushion your skull from impact.
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 other than ACH blunt trauma protection pads, you
are missing critical protection for your brain.
systems can be fine on comfort, but offer MUCH less blunt trauma
protection on impact.
