Note the thin strips of the MIPS layer in this helmet, raising questions about how effective it would be.
POC has a liner partially composed of a honeycomb material.
MIPS has not yet hit the mass market big box stores where most helmets are sold in the US.
Manufacturers are looking at other technologies with similar effects, hoping to mitigate rotational injury, add to the price tag and sell new helmets. Beginning in 2015, Smith had models that use collapsible plastic modules looking like hollow straws in place of foam, but with some standard EPS foam still included in the liner.
There are unpublished indications that the lightest and thinnest helmets do not perform well when impact levels exceed those required by the CPSC standard.
