I am starting to see more and more of these Chinese knock-off "OPS CORE" and "AIRFRAME" STYLE helmets.
Our very own gov't purchasing agents actually thought they would be saving the US Government money by purchasing these instead of OPS CORE & AIRFRAME helmets!
The purchasing agents don't know diddly squat except what we provide them for specs and they search for that, at the lowest price.
Here is a copy of one of the 'certification letters' they received when asking about independent lab certification.
EDITED TO ADD: The rest of their "independent lab certification"
Written in engrish and copious stamps - it MUST be independently certified.
I believe "RIND" is a mis-translation for SHELL.
